tinned copper or copper tubing can be used
per National Fuel Code, section 2.6.3, providing
gas meets hydrogen sulfide limits, and where
permitted by local codes. Gas piping system
must be sized to provide minimum inlet
pressure (Listed on Data Plate) at the maximum

occur if the pipe is too small.
A manual shutoff valve must be installed
upstream of the appliance. Union tee and
plugged ⁄ " NPT pressure tapping point should

When an appliance is connected to a fixed piping sys-
tem, the installation must conform with local codes,or in
the absence of local codes with the National Fuel Gas
Code, ANSI Z223.1/NFPA 54 or International Fuel Gas
Code.
WARNING
CHECK GAS TYPE: The gas supply must be the
same as stated on the heater's rating plate. If
the gas supply is different, DO NOT INSTALL
THE HEATER. Contact your dealer for the
correct model.
IMPORTANT: Loosen the pipe adapter on the flex tube
before installing to the system piping.
Always use an external regulator for all propane/LPG heat-
ers only, to reduce the supply tank pressure to a maximum
of 13" w.c. This is in addition to the internal regulator in the
heater valve.
When tightening the joint to the valve, hold the valve
securely to prevent movement.
Test all gas joints from the gas meter to the heater valve for
leaks using a gas analyzer or soap and water solution after
completing connection. DO NOT USE AN OPEN FLAME.
WARNING
Connecting directly to an unregulated
propane/LP tank can cause an explosion.
DO NOT USE OPEN FLAME TO CHECK
FOR GAS LEAKS.
