der Connecting to Gas Supply,
1. Disconnect appliance with its appliance main
gas valve (control valve) and equipment
shutoff valve from gas supply piping system.
Pressures in excess of 1/2 psig will damage
heater regulator.
2. Cap off open end of gas pipe where equipment
shutoff valve was connected.
3. Pressurize supply piping system by either
opening propane/LP supply tank valve for
propane/LP gas or opening main gas valve
located on or near gas meter for natural gas
or using compressed air.
4. Check all joints of gas supply piping system.
Apply noncorrosive leak detection uid to all
joints. Bubbles forming show a leak.
5. Correct all leaks at once.
6. Reconnect heater and equipment shutoff
valve to gas supply. Check reconnected t-
tings for leaks.
1. Close equipment shutoff valve (see Figure 8).
2. Pressurize supply piping system by either
opening propane/LP supply tank valve for
propane/LP gas or opening main gas valve
located on or near gas meter for natural gas
or using compressed air.
INSTALLATION
Continued
Check your building codes for any special re-
quirements for locating equipment shutoff valve
to replaces.
Apply pipe joint sealant lightly to male NPT
threads. This will prevent excess sealant from
going into pipe. Excess sealant in pipe could result
in clogged heater valves.
We recommend that you install a sediment trap in
supply line as shown in Figure 7, page 8. Locate
sediment trap where it is within reach for clean-
ing. Install in piping system between fuel supply
and heater. Locate 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.
