If the factory-built fireplace has no gas acc
ess hole(s) provided, and access hole 1.5” or
less may be drilled through the lower sides or bottom of the firebox in a proper work-
manship like manner. This access hole must be plugged with non-combustible insula-
tion after the gas supply line has been installed.
GAS PRESSURE REQUIREMENTS
A MAJOR CAUSE OF OPERATING PROBLEMS WITH GAS APPLIANCES CAN BE IMPROPER GAS
PRESSURE!
Such problems as changes in flame color or configuration, gas pilot or burner outages, intermittent op-
eration, changes in heat output, excessive burner noise, etc. are nearly always the result of changes in
gas pressure or improper gas pressure at the time of the installation. The most important item to
check during the installation and the first thing to check when problems occur is gas pressure!
Gas supplies normally enter a residence at 1/2 PSI (13" - 15" W.C.) (3. KPA). A regulator is then
placed inside the residence, which drops this pressure to 7" W.C. (1.8 KPA) (Nat. Gas). This "inches to
inches" regulator is of adequate capacity to service the gas appliances (such as dryer, furnace, etc.). If
this regulator's capacity is not sufficient to add the Gas Fireplace, an additional "inches to inches" regu-
lator must be installed for the Fireplace. EXCEPTION: Some codes allow 2-PSI (1.4KPA) supplies to en-
ter the residence, in which case "pounds to inches" regulators are used.
The following table provides information on correct gas pressure requirements. Be sure your gas sup-
plier or plumber carefully follows this table.

TURN GAS VALVE KNOB TO "HIGH" POSITION. GAS PRESSURES MAY VARY PLUS OR MINUS 5%.
*NOTE: FOR HIGH ALTITUDE (ABOVE 5.000 FEET) SOME VARIATIONS IN AIR SHUTTER SETTINGS MAY BE REQUIRED.
Manifold pressure must be taken at the MANIFOLD" tap and inlet pressure at the "SUPPLY" tap with the burner
operating by a qualified installer.
1. Make sure any gas supply shut-off cocks are open.
