PART 1: GENERAL SAFETY INFORMATION
A. PRECAUTIONS
DO NOT USE THIS APPLIANCE IF ANY PART HAS BEEN UNDERWATER. Immediately call a qualified
service technician. Replace any part of the control system or oil control that has been under water.
If the heater is exposed to the following, do not operate until all corrective steps have been made by a
qualified serviceman.
1. FIRE
2. DAMAGE
3. FIRING WITHOUT WATER
4. SOOTING
5. SUBMERSION IN WATER
The heater must be protected from freezing downdrafts during shutdown periods.
B. CHEMICAL VAPOR CORROSION
Corrosion of the flueways and vent system may occur if combustion air contains certain chemical vapors
which break down into acids at high temperature. Such corrosion may result in failure of burner and risk
of asphyxiation.
Examples of potentially corrosive materials include: Spray can propellants, cleaning solvents, refrigerator
and air conditioning refrigerants, swimming pool chemicals, calcium and sodium chloride (water softener
salt), waxes, and process chemicals. Do not store products of this sort near the heater.
Also, air which is brought in contact with the heater should not contain any corrosive chemicals. If
necessary, uncontaminated air should be obtained from remote or outside sources.
NOTE: DAMAGE TO THE WATER HEATER CAUSED BY EXPOSURE TO CORROSIVE VAPORS IS
NOT COVERED BY WARRANTY.
(Refer to the limited warranty for complete terms and conditions).
