INSTALLATION
CONNECTING TO GAS SUPPLY USING RIGID PIPE
WARNING: A qualified service technician must connect heater to gas supply. Follow all local
codes.
WARNING: Do not overtighten gas connections.
CAUTION: Check your gas line pressure before connecting heater to gas line. Gas line pressure
must be a minimum 11" WC for LP with a max pressure of 14"WC. If gas line
pressure is higher, heater regulator damage could occur.
CAUTION: Never connect heater directly to an LP supply. Install the external regulator between
the heater and gas supply if not using the provided gas hose assembly in an
ice house application.
CAUTION: Avoid damage to regulator. Hold gas regulator with wrench when connecting into gas
piping and/or fittings.
CAUTION: Use pipe joint sealant that is resistant to gas (Propane or Natural Gas).
IMPORTANT: Install an equipment shutoff valve in an accessible location. The equipment shutoff
valve is for turning on or shutting off the gas to the appliance.
Apply pipe joint sealant lightly to male threads. This will prevent excess sealant from going
into pipe. Excess sealant in pipe could result in clogged heater valves.
Install sediment trap in supply line as shown
(See Fig. 17). Place sediment trap where it is
within reach for cleaning. Place sediment trap
where trapped matter is not likely to freeze. A
sediment trap traps moisture and contaminants.
This keeps them from going into heater controls.
If sediment trap is not installed or is installed
wrong, heater may not run properly.
CHECKING GAS CONNECTIONS
WARNING: Test all gas piping and connections for leaks after installing or servicing. Correct all
leaks immediately.
WARNING: Never use an open flame to check for a leak. Apply a 50/50 mixture of liquid soap and
water to all joints. If bubbles form, there may be a leak. Correct all leaks immediately.
Pressure Testing Gas Supply Piping System
Test Pressures In Excess Of 1/2 PSIG ( 3.5kPa )
The appliance and its appliance main gas valve must be disconnected from the gas supply piping
system during any pressure testing of that system at test pressures in excess of ½ psi (3.5 kPa).
Pressure Testing Gas Supply Equal To or less than
1/2 PSIG ( 3.5kPa )
The appliance must be isolated from the gas supply piping system by closing its equipment shut-off
valve during any pressure testing of the gas supply piping system at test pressures equal to or less
than ½ psi (3.5 kPa).
