Gas Line Installation

! This appliance must be installed in accordance with all local codes, if any; if not, follow ANSI Z223.1
and NFPA 54(88) in the USA and B-149 in Canada.
! The heater and gas control valve must be disconnected from the gas supply piping during any
pressure testing of that system at test pressures in excess of 1/2 psig (3.45 kPA). For pressures
under 1/2 psig (3.45 kPA), isolate the gas supply piping by closing the manual shutoff valve.
• Leak test all gas line joints and the gas control valve prior to and after starting the heater.

Gas Line Connection

• The location of the gas inlet is shown below
• A manual shutoff valve is required within 3' of the fireplace. It should be placed upstream of the flex
line (if used) and may be installed behind the access door inside the heater. T-Handle gas cocks are
required in Massachusetts in compliance with code 248CMR.
Shutoff Valve
3-3/8"
With the optional gas inlet pipe,
the inlet is located 3" (76 mm)
behind the fireplace opening
and 14-1/2" (318 mm) to the left
of center and 1-1/2" (38 mm)
above the base.
Shutoff Valve
Fuel
• This heater is designed for natural gas but can be converted to propane. Check the sticker on the top
of the gas control valve to make sure the correct fuel is used.

Gas Inlet Pressure

? If the pressure is not sufficient, make sure the piping used is large enough and the total gas load for
the residence does not exceed the amount supplied.
? The supply regulator (the regulator that attaches directly to the residence inlet or to the propane tank)
should supply gas at the suggested input pressure listed above. Contact the local gas supplier if the
regulator is at an improper pressure.
