BH-SERIES INSTALLATION, OPERATION AND SERVICE MANUAL

SECTION 2: INSTALLER RESPONSIBILITY
The installer is responsible for the following:
• To install the heater, as well as the gas and
electrical supplies, in accordance with applicable
specifications and codes. Roberts-Gordon LLC
recommends the installer contact a local Building
Inspector or Fire Marshal for guidance.
• To use the information given in a layout drawing
and in the manual together with the cited codes
and regulations to perform the installation.
• To install the heater in accordance with the
clearances to combustibles.
• To furnish all needed materials not furnished as
standard equipment.
• To plan location of supports.
• To provide access on all sides for burner servicing
and removal.
• To provide the owner with a copy of this
Installation, Operation and Service Manual.
• To never use heater as a support for a ladder or
other access equipment and never hang or
suspend anything from heater.
• To ensure there is adequate air circulation around
the heater and to supply air for combustion,
ventilation and distribution in accordance with
local codes.
• To safely and adequately install heater using
materials with a minimal working load of 75 lbs
(33 kg).
• To ensure the heater is placed in an approved
application.
2.1 Wall Tag
A laminated wall tag is available for the heater as
a permanent reminder of the safety instructions and
the importance of the required clearances to
combustibles. Please contact Roberts-Gordon or
your ROBERTS GORDON® independent distributor
to obtain the wall tag. Affix the tag by peeling
off the backing of the adhesive strips on the rear
surface and position the tag on a wall near the
heater (e.g. thermostat or ROBERTS GORDON®
Controller).
A copy of the wall tag (P/N 91037912) is illustrated on
the back cover. For an immediate solution, you may
affix this copy on the wall near the heater.
Know your model number and installed configuration.
Model number and installed configuration are found on
the burner and in the Installation, Operation and
Service Manual. See Page 6, Figure 3 through Page
9, Figure 12. Write the proper clearance dimensions in
4 of 59

permanent ink according to your model number and
configuration in the open spaces on the tag.
2.2 Corrosive Chemicals

CAUTION

Product Damage Hazard
Do not use heater in area containing
corrosive chemicals.
Refer to appropriate Material Safety Data
Sheets (MSDS).
Failure to follow these instructions can result
in product damage.
Roberts-Gordon LLC cannot be responsible for
ensuring that all appropriate safety measures are
undertaken prior to installation; this is entirely the
responsibility of the installer. It is essential that the
contractor, the sub-contractor, or the owner identifies
the presence of combustible materials, corrosive
chemicals or halogenated hydrocarbons* anywhere
in the premises.
* Halogenated Hydrocarbons are a family of
chemical compounds characterized by the
presence of halogen elements (fluorine, chlorine,
bromine, etc.). These compounds are frequently
used in refrigerants, cleaning agents, solvents, etc.
If these compounds enter the air supply of the
burner, the life span of the heater components will
be greatly reduced. An outside air supply must be
provided to the burners whenever the presence of
these compounds is suspected. Warranty will be
invalid if the heater is exposed to halogenated
hydrocarbons.
2.3 National Standards and Applicable Codes
All appliances must be installed in accordance with
the latest revision of the applicable standards and
national codes. This refers also to the electric, gas
and venting installation. Note: Additional standards
for installations in public garages, aircraft hangars,
etc. may be applicable.

SECTION 3: CLEARANCES TO COMBUSTIBLES

SECTION 3: CLEARANCES TO COMBUSTIBLES
3.1 Required Clearances to Combustibles
Clearances are the required distances that
combustible objects must be away from the heater to
prevent serious fire hazards. Combustibles are
materials that may catch on fire and include common
items such as wood, paper, rubber, fabric, etc.
Maintain clearances to combustibles at all times
for safety.
Clearances for all heater models are located on the
burner of the heater and on Page 6, Figure 3 through
Page 9, Figure 12 in this manual. Check the
clearances on each burner for the model heater
being installed to make sure the product is suitable
for your application and the clearances are
maintained. Read and follow the safety guidelines
below:
• Keep gasoline or other combustible materials
including flammable objects, liquids, dust or
vapors away from this heater or any other
appliance.
• The stated clearances to combustibles represents
a surface temperature of 90° F (50° C) above
room temperature. Building materials with a low
heat tolerance (such as plastics, vinyl siding,
canvas, tri-ply, etc) may be subject to degradation
at lower temperatures. It is the installer’s
responsibility to assure that adjacent materials
are protected from degradation.
• Maintain clearances from heat sensitive
equipment and workstations.
• Maintain clearances from vehicles parked below
the heater.
• Maintain clearances from swinging and overhead
doors, overhead cranes, vehicle lifts, partitions,
storage racks, hoists, building construction, etc.
• In locations used for the storage of combustible
materials, signs must be posted to specify the
maximum permissible stacking height to maintain
required clearances from the heater to the
combustibles. Signs must be posted adjacent to
the heater thermostat. In the absence of a
thermostat, signs must be posted in a
conspicuous location.
• Consult local Fire Marshal, Fire Insurance Carrier
or other authorities for approval of proposed
installation when there is a possibility of exposure
to combustible airborne materials or vapors.
• Hang heater in accordance to the minimum
suspension requirements on Page 15, Figure 14.

WARNING

Fire Hazard
Keep all flammable objects, liquids and
vapors the minimum required clearances to
combustibles away from heater.
Some objects will catch fire or explode when
placed close to heater.
Failure to follow these instructions can result
in death, injury or property damage.
• If the radiant tubes must pass through the building
structure, be sure that adequate sleeving and fire
stop is installed to prevent scorching and/or fire
hazard.

SECTION 8: VENTING

WARNING

Any portion of vent pipe passing through a
combustible wall must have an approved thimble
to conform with the above listed codes.
Vent pipe must be sloped downward away from the
heater 1/2'' (1 cm) for every 20' (6 m).

Carbon Monoxide Hazard
Heaters installed unvented must be interlocked
with sufficient building exhaust.
Heaters must be installed according to the
installation manual.
Failure to follow these instructions can result
in death or injury.

WARNING

The heater may be individually vented or common
vented. When venting horizontally, a maximum of two
heaters can be commonly vented. See Page 37,
Section 8.9. When venting vertically, a maximum of
four heaters can be commonly vented. See Page 38,
Section 8.10.
The heater may also be installed unvented in certain
circumstances according to building ventilation
codes. Refer to the above codes and Page 36,
Section 8.2 for further information. Unvented
operation also requires compliance with the
clearances to combustibles given on Page 9, Figure
12.
The bottom of the vent or air intake terminal shall not
be located less than 1' (0.3 m) above grade level.

Cut/Pinch Hazard
Wear protective gear during installation,
operation and service.
Edges are sharp.
Failure to follow these instructions can result
in injury.

The vent shall not terminate less than 7' (2.1 m)
above grade where located adjacent to public
walkways.
Vent terminal must be installed at a height sufficient
to prevent blockage by snow, and building materials
protected from degradation by flue gases.
Secure all joints with #8 x 3/8 sheet metal screws.
Seal all joints with high temperature silicone sealant.

8.1 Venting
This heater must be vented in accordance with the
rules contained in this manual and with the following
national codes and any state, provincial or local
codes which may apply:
United States: Refer to National Fuel Gas Code
NFPA 54/ANSI Z223.1 - latest revision.
Canada: Refer to Natural Gas and Propane
Installation Code CSA B149.1 - latest revision.

Vent terminal must be beyond any combustible
overhang.
8.1.1 United States Requirements
Vent must terminate at least 3' (0.9 m) above any
forced air inlet located within 10' (3.1 m).

Exhaust end of heater will accept a 4'' (10 cm) vent
pipe using the vent adapter (P/N 90502700). To
prevent leakage of condensation, install the vent

BH-SERIES INSTALLATION, OPERATION AND SERVICE MANUAL

8.2 Unvented Operation
Sufficient ventilation must be provided in the amount
of 4 cfm per 1000 Btu/h firing rate (United States); 3
cfm per 1000 Btu/h firing rate (Canada).
Use of optional outside combustion air is not
recommended with unvented heaters.
If exhaust fans are used to supply ventilation air, an
interlock switch must be used to prevent the heater
from coming on when the fans are off. This may be
done using a pressure switch.

A vent shall not extend less than 2' (0.6m) above the
highest point where it passes through a flat roof of a
building.
8.5 Unvented Operation Tube Termination
Turndown type vent terminal with a screen must be
installed at the exhaust end of the tube. Vent terminal
design shall not incorporate backdraft flap.
FIGURE 22: Tube Termination

8.3 Horizontal Venting
In noncombustible walls only, vent terminal
(P/N 02537801-1P) may be used.
For 4" (10 cm) vents in either combustible or
noncombustible walls, use Tjernlund VH1-4 (P/N
90502100) or equivalent, insulated vent terminal.
Follow the manufacturer's instructions for proper
installation.
For 6" (15 cm) common vents in either combustible
or noncombustible walls, use Tjernlund VH1-6 (P/N

SECTION 9: GAS PIPING

WARNING

Fire Hazard
Tighten gas hose fittings to connect gas
supply according to Figure 23.
Gas hose can crack when twisted.
Gas hose moves during normal operation.
Use only 36" (91 cm) long connector of 1/2" or
3/4" nominal ID.
Connector supplied with heater for U.S.
models (not with Canadian models).
Failure to follow these instructions can result
in death, injury or property damage.

WARNING

Explosion Hazard
Leak test all components of gas piping
before operation.

Install the gas hose as shown on Page 42, Figure 23.
The gas hose accommodates expansion of the
heating system and allows for easy installation and
service of the burner. Before connecting the burners
to the supply system, verify that all high pressure
testing of the gas piping has been completed.
There is an expansion of the tube with each firing
cycle; this will cause the burner to move with respect
to the gas hose. This can cause a gas leak resulting
in an unsafe condition if the gas connection is not
made strictly in accordance with Figure 23 on Page
42.
Meter and service must be large enough to handle all
the burners being installed plus any other connected
load. The gas hose which feeds the system must be
large enough to supply the required gas with a
maximum pressure drop of 1/2" wc. When gas piping
is not included in the layout drawing, the local gas
supplier will usually help in planning the gas piping.
Gas lines must meet applicable codes:
United States: The Flexible Stainless Steel Gas
Hose (US models) supplied with the heater is certified per the Standard for Connectors for Gas Appliances, ANSI Z21.24/CSA 6.10 - latest revision.
Canada: The Rubber Type 1 Gas Hose (Canadian
models) optional with the heater is certified as being
in compliance with the Standard for Elastomeric
Composite Hose and Hose Couplings for Conducting
Propane and Natural Gas, CAN/CGA 8.1 - Latest
revision.
• Check the pipe and tubing ends for leaks
before placing heating equipment into
service. When checking for gas leaks, use a
soap and water solution; never use an open
flame.

Gas can leak if piping is not installed
properly.
Do not high pressure test gas piping with
heater connected.
Failure to follow these instructions can result
in death, injury or property damage.
