Venting

The venting system is an integral part of the appliance,

The venting system must not be modified in any matter

other than what is specified in these instructions.

This appliance should be installed in a location such that

the vent outlet is located in the following manner:

1. Distances to windows that open, building openings, or

public walkways should be consistent with the National

Fuel Gas Code Z223.1 or CAN/CGA-B149.1 & .2.

,For U.S. installations, the vent system shall terminate

a minimum horizontal clearance of 4' from electric

meters, regulators, and relief equipment. For installa-

tions in Canada, refer to the current CAN/CGA-B149.1

& .2 or with the authorities having local jurisdiction.

3. Flue products will not cause degradation to building

materials.

The unit contains an exhaust blower. The blower draws the

combustion products out of the heat exchanger together

with dilution air and forces the mixture from the unit to the

outside. No special provisions are required for supplying

air for combustion, nor is a chimney required.

The vent outlet must be extended (see Vent Pipe Instal-

lation on page 6).

The venting system is designed for proper operation under

all weather conditions and for winds up to 40 miles per hour.

Existing Venting Systems

When an existing furnace is removed or replaced, the

original venting system may no longer be sized to properly

vent the attached appliances. An improperly sized venting

system can result in spillage of flue products into the living

space, the formation of condensate, leakage, etc. Refer to

the WARNING box in the next column for proper test

procedure.

[, WARNING

CARBON MONOXIDE POiSONiNG HAZARD

Failure to follow the steps outlined below for each

appliance connected to the venting system being

placed into operation could result in carbon monox-

ide poisoning or death.

The following steps shall be followed for each appli-

ance connected to the venting system being placed

into operation, while all other appliances connected to

the common venting system are not in operation:

1. Seal any unused openings in the common venting

system.

,Visually inspect the venting system for proper size

and horizontal pitch, as required in the National

Fuel Gas Code, ANSI Z223.1/NFPA 54 (latest

edition) or the CSA B149.1, Natural Gas and

Propane Installation Codes and these instructions.

Determine that there is no blockage or restriction,

leakage, corrosion, or other deficiencies which

could cause an unsafe condition.

,As far as practical, close all building doors and

windows between the space in which the

appliance(s) connected to the venting system are

located and other spaces in the building.

4. Close fireplace dampers.

,Turn on clothes dryers and any appliance not

connected to the venting system. Turn on any

exhaust fans, such as range hoods and bath-

room exhausts, so they are operating at maxi-

mum speed. Do not operate a summer exhaust

fan.

6. Follow the lighting instructions. Place the unit

being inspected in operation. Adjust the thermo-

stat so appliance is operating continuously.

,Test for spillage from draft hood equipped appli-

ances at the draft hood relief opening after

5 minutes of main burner operation. Use the flame

of a match or candle.

,If improper venting is observed during any of the

above tests, the venting system must be corrected

in accordance with the National Fuel Gas Code,

ANSI Z223.1/NFPA 54 (latest edition) and/or the

CSA B149.1, Natural Gas and Propane Installa-

tion Codes.

,After it has been determined that each appliance

remaining connected to the venting system

properly vents when tested as outlined above,

return doors, windows, exhaust fans, fireplace

dampers, and any other gas-fired burning appli-

ance to their previous conditions of use.

Vent Pipe Installation

Determining the length of the vent pipe extension is

dependent upon which wall sleeve accessory is installed

at the job site for each particular installation.

Access vent pipe at the side of the unit that will face

the outdoors.

The vent pipe and vent pipe extension is located to

the right of the outdoor fan (see Figure 3).

3. Remove the 5/16" screw used to mount the vent pipe

assembly to the mounting bracket. Keep this screw.

,Five holes have been drilled into the vent extension

(see Figure 4). Four of those holes are provided so

that the vent can be extended the necessary length

required for the installation. The wall sleeve that is

installed determines which of these clearance holes

should be used. Using Table 2 and Figure 4, deter-

mine which clearance hole should be used to position

the vent extension properly. Slide the vent extension

outward and line up the correct clearance hole on the

vent extension with the hole in the vent pipe and the

hole in the mounting bracket.

,Re-install the 5/16" screw that was removed in Step 3.

Thread the screw first through the clearance hole in

the mounting bracket, the proper clearance hole in the

vent extension, and into the engagement hole in the

vent pipe. The length of the vent pipe extension that

Installing and Securing Unit to Wall Sleeve

Before installing and securing the unit to the wall sleeve,

make sure that the proper louver kit is installed. Due the

high temperatures of the combustion products released

from the gas vent, MGE gas package units require the use

of either an aluminum louver kit or special MGE polypro-

pylene louver kit (see ACCESSORIES on page 17).

1. Make sure the gaskets attached to the sleeve are not

damaged.

,Verify divider panel is positioned properly. Figure 5

shows the correct position for 60" and 64" tall units

(flange pointing up). For 58" tall units, the divider panel

should be positioned so the flange points down.

Page 6 #46977A006

Positioning Divider Panel

Divider must be positioned this way (flange up)

for 60" and 64" tall units.

Divider must be positioned this way (flange down)

for 58" tall units.

Figure 5

Place MGE unit into the wall sleeve. Lift leading end

of unit and walk unit onto the sleeve. Once in the

sleeve, lower unit into position. This prevents damage to

the base pads. Assure that unit is level and completely

seated against the gaskets on the wall sleeve.

.Use the two installation brackets to secure the unit to

the wall sleeve (see Figure 6). The units are shipped

with the brackets placed loose on the unit top panel,

beneath packaging. Hook each bracket into the front

edge of the wall sleeve side. Position the bracket so it

can be bent around the front corner of the unit. Remove

one of the two screws in that position on the unit. Line

up one of the holes in the installation bracket with the

screw hole and attach the bracket to the unit with that

screw. Make sure to fasten tight enough that the seal is

maintained. Trim off excess bracket if applicable.

Inspect the fit up of the unit to the wall sleeve. Verify

that the gaskets of the wall sleeve make a complete

seal to the unit paying particular attention to top and

bottom corners of unit to sleeve seal. Caulk if needed.

Refer to unit rating plate to make sure the furnace is

equipped to burn the gas supplied (natural or propane).

Gas supply piping should be installed in accordance with

local codes and the regulations of the utility. Piping must

be of adequate size to prevent undue pressure drop.

Consult the local utility or gas supplier for complete details

on special requirements for sizing gas piping.

If local codes allow the use of a flexible gas appliance

connector, always use a new listed connector. Do not use

a connector which has previously serviced another gas

appliance.

Pipe connections must be tight, and a non-hardening pipe

compound resistant to liquefied petroleum gases should be

used.

Connect the gas pipe to the furnace controls providing a

ground joint union as close to the controls as is possible to

facilitate removal of controls and manifold. Provide a drip

leg on the outside of the furnace. A manual shutoff valve

shall be installed in the gas line, outside the unit, 5' above

the floor, or in accordance with any local codes. A test

gauge connection must be installed with a 1/8" NPT

plugged tapping immediately upstream of the shutoff valve

(refer to Figure 8).

The furnace must be isolated from the gas supply piping

system by closing the individual manual shutoff valve

Heating

1. Turn on main power supply.

2. Open manual gas shutoff valve.

3. Set thermostat system to "HEAT".

4. Set thermostat to temperature desired.

Sequence of Operation

1. Thermostat calls for heat.

2. Combustion blower starts and proper air flow is

proven by the pressure switch closing.

3. Blower continues to operate for 30 seconds prior to

the burners lighting.

4. Ignition control begins spark and opens gas valve. The

burners are lit. Ignition is proved through flame sensor.

5. Circulating air blower starts 30 seconds after the

burners light.

6. When the thermostat is satisfied, the burners and

combustion blower shut off.

7. Circulating air blower will shut off 120 seconds later.

Ifthe burners should fail to ignite, the ignition control will try

to ignite the burners a total of three times. Should the

burners fail to ignite within the three trials for ignition, the

ignition control will lock out for 1 hour before beginning

another ignition cycle. To reset the control, turn the thermo-

stat down or off for 10 seconds and then set to desired

setting. At this time, the ignition sequence will try again.

Cooling

1. Set thermostat system switch to "COOL".

2. Set thermostat to temperature desired.

NOTE: When Y is energized, the combustion blower will

operate for 10 seconds. The purpose of this action is to

deter insect nesting in the flue pipe.

To Shut Down Unit

For temporary or short periods of shutdown, set the

thermostat system switch to "OFF". For a prolonged

period of shutdown, set the thermostat system switch to

"OFF" and turn off the electrical power supply and the gas

supply to the unit.

Adjustments -Heating Section

Temperature Rise

At time of installation, the temperature rise must be adjusted

to be within the range specified on the unit rating plate.

Checking and Adjusting Gas input

The gas input must not exceed the figures shown on the

rating plate. The unit is equipped for rated inputs with

manifold pressures of: 3.5" W.C. for natural gas and 10.0"

W.C. for propane. The furnace requires conversion for use

with propane (a propane conversion kit is available from

the manufacturer).

The manifold pressure can be measured by removing the

pipe plug in the downstream side of the gas valve and

connecting a water manometer or gauge.

Only small variations in gas input may be made by

adjusting the regulator. In no case should the final

manifold pressure vary more than 0.3" W.C. for

natural gas or 0.7" W.C. for propane.

To adjust the regulator, turn the adjusting screw on the

regulator clockwise to increase pressure and input or

counterclockwise to decrease pressure and input.

For Natural Gas: Check the furnace rate by observing the

gas meter, when available, making sure all other gas

appliances are turned off. The test hand on the meter

should be timed for at least one revolution. Note the

number of seconds for one revolution.

BTU/HR =Cubic Feet Per Revolution × 3600 × Heating

iNPUT #Seconds Per Revolution Value

The heating value of the gas can be obtained from the

local utility company.

For Propane Gas: The only check for the furnace rate is

to properly adjust the manifold pressure using a manom-

eter and the information found in Table 5 on page 14.

Typical manifold set point for installations at altitudes from

0 to 4500' above sea level is 10.0" W.C.

Adjustments -Cooling Section

No adjustments are required or should be attempted

regarding any of the components of the cooling system.

A fixed temperature limit control is provided which will shut

off the gas to the burners if the unit is overheated for any

reason. The control must not be adjusted or relocated.

Rollout Switch

If for any reason the exchanger were to become blocked,

there is a temperature sensitive switch located above the

burners that will turn off the burners. After correcting the

problem, this switch must be manually reset by pressing

the button on top of it.

High Altitude

In both the United States and Canada, this unit is ap-

proved for operation at altitudes from 0 to 4500 feet above

sea level without any required modifications. From 4500 to

7500 feet, the gas manifold pressure needs to be adjusted

according to the information shown inTable 5. To adjust the

Page14 #46977A006

manifoldpressure,refertoprevioussectionChecking and

Adjusting Gas Input on page 13. For installations above

7500 feet, call Technical Service at 1-800-448-5872 ext.

2610 for assistance.

Installation and Operation in Extremely Cold

Weather Areas

In areas where extremely cold outdoor temperatures

(below - 20°F) can be expected, some additional installa-

tion and operating precautions should be taken. The

following precautions are designed to prevent possible

vent system ice blockage that could result in safety

shutdown of the burners:

,Adjust to the highest achievable temperature rise

within the rise and static pressure ranges specified on

the rating plate. Depending on specific model, it may

be possible to change to a lower heating blower speed

tap to get a higher temperature rise. This also in-

creases comfort.

2. Make sure there are no leaks of outside air into the

return air system.

3. Keep the outside louver grille as free as possible of

any ice that may form and obstruct the flue outlet.

MAINTENANCE Cooling System

Burners

The burners can be removed for cleaning or changing

orifices. To remove the burners:

1. Disconnect electrical service and turn off gas to the

appliance.

2. Disconnect the high voltage (spark plug) wire and the

flame sensor wire (Sl) from the ignition control.

3. Remove spark and sense rods.

4. Remove the four screws that mount the burner right

side plate (houses the spark/sense probes).

5. Carefully remove the burner right side plate.

6. Burners are now exposed and can be individually

removed from assembly by removing the two screws

that hold each burner in the burner rack.

Burners can be cleaned using a bottle brush.

Orifices are threaded into the gas manifold and can be

removed by unscrewing.

When replacing the burner tray assembly, take care in

installing the sense and spark rods back into the burner

plate. Reconnect the spark and sense wires.

Heat Exchanger

The heat exchanger should be inspected periodically and

cleaned if necessary. If cleaning is necessary, use a stiff

brush with a wire handle to remove scale and soot. While

cleaning the heat exchanger, the vent extension tube

should also be cleaned. Remove the four screws on the

combustion blower mounting plate and take out the blower.

Use a brush to clean the vent extension tube.

The refrigeration system normally requires no mainte-

nance since it is a closed, self-contained system. Periodic

maintenance is limited to:

Cleaning the air filter. Follow directions noted on the

filter and label attached to the access panel.

Cleaning the condenser coil if covered with any

foreign material, lint, leaves, or other obstructions.
