CHECK GASINPUT (C_.JTYGASE._ONLY)

The inlet to the unit, may be checked by using

the gas meter as follows:

1. Turn off all other gas appliances cormeeted to

the meter.

2. Start the heating uni_ -- and set the thermo.

_tat so that the main burner is ,m.

3. Wazch the "smallest" _ on the &,as mater

(the one whose hand is r_'olving fastest). Count

(with the second land of a watch or clock) the

exact number of seconds it takes forthe hand of this

dial to make one _ul]revolution.

4. Now look to see what one revolu_on of this

band indicates, as marked on the dial. On some

•meters the "smartest" dial will read "ONE FOOT,"

or it m_ght reed "QUARTE_ FOOT," or "5 FEET."

•A typical meter is i|]ustrated here.

The gas piping to the heating unit Should be an

independent line direct from the gas meter to the

unit--Is insure an unrestricted gas flow and proper

burner operation. In addition, the pipe for this

li_e _nust be of ample size. Its size will depend

upon the length of the line (from meter to unit),

the number of fittings required (elbows. couplings,

etc), the req,dred maximum BTU/IffR. input of

the unit• and the specific gravity of the gas used.

H you will req_dre more than 60 feet of piping

and/or more than 6fittir_s between your meter

and the "T'" (See Fig. 4, Co,meeting the Gas Pip-
