Gas Line Installation
•
The gas line must be installed in accordance with all local codes and the requirements listed below.
In the absence of local codes, follow ANSI 223.1 in US/Canada or AS/NZS 5601.1 in Australia.
!
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.
•
This heater is designed for natural gas but can be converted to propane. Check the sticker on top of
the gas control valve to verify the correct fuel is used (see page 4).
•
Leak test all gas line joints and the gas control valve prior to and after starting the heater.
•
The location of the gas inlet is shown below
•
A manual shutoff valve is required for installation (it must be located within 3’ of the heater).
T-Handle gas cocks are required in Massachusetts in compliance with code 248CMR.
•
This stove is shipped with a 16” (406mm) long, 3/8” diameter flex gas line attached to an elbow on the
gas control valve (see illustration below for location). The flex accepts a 3/8” flare fitting.

If the pressure is not sufficient, make sure the piping used is large enough, the supply regulator is
adequately adjusted, 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.
