Installation and start up of this water heater requires abilities
and skills equivalent to that of a licensed tradesman in the field
involved, see Qualifications on page 6.
Do not place the water heater in operation if any part has been
under water. Immediately call a qualified service technician to
inspect the water heater and to replace any part of the control
system and any gas control which has been under water.
light the water heater in accordance with the lighting and
operation Instruction label on the water heater and in this manual
beginning on page 54.
The water heaters covered by this manual are equipped with
an electronic control system (see page 42) which automatically
sequences the Combustion blower, pre and post purging of the
combustion chamber, the Hot Surface Igniter, the 24 Volt Gas
Valve, main burner ignition, and flame sensing. The control
system will lock out after three unsuccessful ignition attempts.
before attempting start up, thoroughly study and familiarize
yourself with the exact Sequence of operation, see the written
Sequence of operation on page 55 and the Sequence of
operation Flow Chart on page 56.
be certain that the water heater is full of water, that air is purged
from the gas and water lines and that there are no leaks in the
gas and water lines. ensure all inlet water valves are open.

before filling the water heater with water the pump station storage
tank loop must be connected to the water heater.
Plug the pump station solar loop connections if they are not being
used in your application.
1. Close the heater drain valve. The drain valve is on the lower
front of the water heater.
2. open the cold water supply to the water heater. NoTe:

3. Fill the water heater until a constant flow of water runs out of
an opened hot water faucet. This will let out air from the water
heater and piping. Close the water faucet and solar loop air
vent after all air has been purged and the water comes out
with constant flow.
4. Check all the new piping for leaks. Fix as needed.

suPPLy gAs LInE PuRgIng
Fire or Explosion Hazard
Read instruction manual before
installing, using or servicing
water heater.
To avoid risk of fire or explosion purge discharge must not
enter into confined areas or spaces where ignition can occur.
The area must be well ventilated and all sources of ignition
must be deactivated or removed.
Gas line purging is required with new piping or systems in
which air has entered.
Use only the gas shown on the water heater rating label.
Keep ignition sources away from faucets after extended
periods of non-use.
1. Close the main Gas Shutoff Valve, see Figure 48 on page
37.
2. Purge all air from the supply gas line up to the water heater’s
main Gas Shutoff Valve.
3. When all air has been purged from the supply gas line,
tighten all supply gas line connections.
4. Check for gas leaks, see Gas line leak Testing on page 38,
and repair any leaks found.

• Two u-tube manometers, recommended ranges; 0-14” W.C.
(0-3.5 kPa) and 0-35” W.C. (0-8.7 kPa) or pressure gauges.
• Two digital manometers can be used in place of u-tube
manometers or pressure gauges. recommended ranges;
-14.00 to +14.00” W.C. (0-3.5 kPa) resolution 0.01” W.C.
and 0-35” W.C. (0-8.7 kPa) resolution 0.10” W.C.
nOtE: All test equipment must be acclimated to ambient
temperature before calibration and use.
PREPARAtIOn
1. using the control system menus, change the operating Set
Point to the lowest temperature setting, see operating Set
Point And Differential Adjustment on page 45.
2. Turn the water heater’s on/off switch to the “off” position.
3. Close the main Gas Shut off Valve, see Figure 48 on page
37.
4. Wait five (5) minutes for any residual gas to clear.
5. Connect one manometer (higher range) to an available test
port for the supply gas pressure to the water heater:
on SSF/SSX 100 models there is a 1/8" NPT Tee fitting
and pipe nipple installed for the low Gas Pressure switch
on the inlet side of the 24 Volt Gas Valve with a 1/8" pipe
plug for this purpose. remove the 1/8 inch pipe plug from the
bottom of the Tee fitting and install a barb fitting to connect
the manometer sensing tube, see Figure 53 on page 51.
