INSTALLATION
*A CSA/AGA design-certified equipment shutoff valve with 1/8" NPT tap
is an acceptable alternative to test gauge connection. Purchase the
optional CSA/AGA design-certified equipment shutoff valve from
your dealer.
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.
Install sediment trap in supply line
as shown in Figure 12. Locate
sediment trap where it is within
reach for cleaning. Locate
sediment trap where trapped
matter is not likely to freeze. A
sediment trap traps moisture and

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.
Pressure Testing Gas Supply
Piping System
Test Pressures In Excess Of
1/2 PSIG (3.5 K Pa)
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 using compressed air
or opening main gas valve
located on or near gas meter.
4. Check all joints of gas supply
piping system. Apply mixture of
liquid soap and water to gas
joints. Bubbles forming show
a leak.
5. Correct all leaks at once.
6. Reconnect heater and equipment
shutoff valve to gas supply. Check
reconnected fittings for leaks.
Test Pressures Equal To or
Less Than 1/2 PSIG (3.5 K Pa)
1. Close equipment shutoff valve
(see Figure 13).
2. Pressurize supply piping system
by either using compressed air
or opening main gas valve lo
cated on or near gas meter.
3. Check all joints from gas mater to
equipment shut off valve (See
Figure14) Apply mixture of liquid
soap and water to gas joints.
Bubbles forming show a leak.
4. Correct all leaks at once.
State of Massachusetts : The instal-
lation must be made by a licensed

CHECKING GAS
CONNECTIONS
WARNING: Test all gas
piping and connections for leaks
after installing or servicing. Correct
all leaks at once.
WARNING: Never use an
open flame to check for a
leak. Apply a mixture of liquid
soap and water to all joints.
Bubbles forming show a leak.
Correct all leaks at once.
contaminants. This keeps them
from going into heater controls. If
sediment trap is not installed or is
installed wrong, heater may
not run properly.
CAUTION: Make sure external
regulator has been installed be-
tween gas supply and heater. See
guidelines under Connecting to Gas
Supply.
