CHECKING GAS CONNECTIONS
INSTALLATION
WARNING: Test all gas piping
and connections for leaks after
installing or servicing. Correct
all leaks at once.
WARNING: Never use an open
ame to check for a leak. Apply a
noncorrosive leak detection uid
to all joints. If bubbles form, there
is a leak. Correct all leaks at once.
The installer must supply an external regula-
tor. The external regulator will reduce incom-
ing gas pressure. You must reduce incoming
gas pressure to between 11" and 14" of water.
If you do not reduce incoming gas pressure,
heater regulator damage could occur. Install
external regulator with the vent pointing down
as shown in Figure 16. Pointing the vent down
protects it from freezing rain or sleet.
Install sediment trap in supply line as shown
in Figure 15. 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 contami-
nants. This keeps them from going into heater
controls. If sediment trap is not installed or is
installed wrong, heater may not run properly.

* Purchase the optional CSA design-certied equipment
shuto valve from your dealer.
Typical Inlet Pipe Diameters
Use 3/8" black iron pipe or greater. Installa-
tion must include an equipment shuto valve,
union, and plugged 1/8" NPT tap. Locate
NPT tap within reach for test gauge hook up.
NPT tap must be upstream from heater (see
Figure 15).
IMPORTANT: Install an equipment shuto
valve in an accessible location. The equip-
ment shuto valve is for turning on or shutting
o 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.
