FOR YOUR SAFETY READ BEFORE OPERATING
WARNING
A. This appliance is equipped with an ignition device which automatically lights the pilot. Do not try to light the pilot by hand.
B. BEFORE OPERATING smell all around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and
will settle on the floor.
WHAT TO DO IF YOU SMELL GAS
. Do not try to light any appliance.
. Do not touch any electric switch; do not use any phone in your building.
. Immediately call your gas supplier from a neighbor's phone. Follow the gas supplier's instructions.
. If you cannot reach your gas supplier, call the fire department.
C. Use only your hand to turn the gas valve knob.
Never use tools. If the knob will not turn by hand, don´t try to repair it, call a qualified service technician. Force or attempted repair may result in
a fire or explosion.
D. Do not use this appliance if any part has been under water.
Immediately call a qualified service technician to inspect the appliance and to replace any part of the control system and any gas control which has
been under water.
If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury, or
loss of life.

after this time you smell gas, STOP and follow “B” in the safety
information on this page. If no gas odor is detected, proceed to
the next step.
5. Turn the gas control knob counter-clockwise to the
“PILOT” position.

COMBINATION SPACE HEATING /POTABLE WATER HEATING SYSTEM
When using this heater as a source of heat for a combination space heating/potable water heating system, be sure to follow manual(s)
shipped with air handler system. Refer to figure 18 page 32. Note the following warnings:
Toxic chemicals, such as those used for boiler treatment, shall NEVER be introduced into this system. This unit may NEVER be
connected to any existing heating system or component(s) previously used with a non-potable water heating appliance.
DO NOT use with piping that has been treated with chromates, boiler seal or other chemicals.
DO NOT add boiler treatment or any chemicals to any heat piping, since the piping contains potable water.
DO NOT use with ferrous piping. The system should be installed only with new piping that is suitable for potable water, such as
copper or polybutylene. DO NOT USE WITH PVC PIPING.
DO NOT use with any pumps, valves, or fittings that are not completely compatible with potable water piping.
DO NOT use valves that may cause excessive restriction to water flow. USE FULL FLOW BALL OR GATE VALVES ONLY.
DO NOT tamper with the thermostat, gas valve, igniter control or temperature and pressure relief valve. Tampering with any of these
components is DANGEROUS and can result in property damage or severe injury. Tampering voids all warranties. Only qualified
personnel should service these components.
DO NOT use 50/50 solder in potable water lines.
IF THE SPACE HEATING system requires water temperatures in excess of 140°F, a mixing valve or other means should be installed in
the domestic (potable) hot water supply to limit the RISK OF SCALD DAMAGE.
SOME JURISDICTIONS may require a backflow preventer in the incoming cold water line to the water heater. ln such cases, the
temperature and pressure relief valve on the water heater may weep or relieve due to expansion of the heated water. A
diaphragm-type expansion tank will normally eliminate this weeping condition. Please read and follow the manufacturer's instructions
for installation of such tanks.
VENTING SYSTEM INSPECTION
Check the draft hood relief opening (Figure 5) using a match flame after 15 minutes of operation. Pass the match flame around the relief
opening of the draft hood. A steady flame drawn into the opening indicates proper draft. If the flame flutters or is blown out this would
indicate spillage and corrective action must be made to the vent. (Figure 5)
At least every 3 months a visual inspection should be made of the venting system. You should look for:
Obstructions which could cause improper venting.
Damage or deterioration which could cause improper venting or leakage of combustion products.
CONDENSATION
Whenever the heater is filled with cold water there will usually be a certain amount of condensation formed while the burner is ON.
Moisture from the products of combustion condenses on the cooler tank surfaces to produce a "sizzling" or "frying" noise. During the
winter months this condition will be more pronounced. Condensation is normal and should not be confused with a leaking tank. The
water will be noted at different times of the year and in varying quantities.
