Reliance Water Heaters D85500PE, D85500NE Propane Installations, High Altitude Installations

See the Circulation Pump Wiring Diagrams (Figure 8, Figure

9)in this manual for electrical hookup information. Install in accordance with the current edition of the National Electrical Code, NFPA 70 or the Canadian Electrical Code, CSA C22.1.

All-bronze circulators are recommended for used with commercial water heaters.

Some circulating pumps are manufactured with sealed bearings and do not require further lubrication. Some circulating pumps must be periodically oiled. Refer to the pump manufacturer’s instructions for lubrication requirements.

Breathing Hazard - Carbon Monoxide Gas

Under no circumstances should the input exceed the rate shown on the water heater’s rating label.

Overfiring could result in damage to the water heater and sooting.

Gas and carbon monoxide detectors are available.

Breathing carbon monoxide can cause brain damage or death. Always read and understand instruction manual.

Propane Installations

INSTALLATIONS ABOVE 2000 FEET (610 METERS) REQUIRE REPLACEMENT OF BURNER ORIFICES IN ACCORDANCE WITH CURRENTEDITION OFTHE NATIONALFUELGAS CODE (ANSI Z223.1). FOR CANADIAN INSTALLATIONS CONSULT CANADIAN INSTALLATIONS CODE CAN/CSAB149.1. FAILURE TO REPLACE ORIFICES WILL RESULT IN IMPROPER AND INEFFICIENT OPERATION OF THE APPLIANCE RESULTING IN THE PRODUCTION OF INCREASED LEVELS OF CARBON MONOXIDE GAS IN EXCESS OF SAFE LIMITS WHICH COULD RESULT IN SERIOUS PERSONAL INJURY OR DEATH.

You should contact your gas supplier for any specific changes which may be required in your area.

As elevation above sea level is increased, there is less oxygen per cubic foot of air. Therefore, the heater input rate should

be reduced at high altitudes for satisfactory operation with the reduced oxygen supply. Failure to make this reduction would result in an over firing of the heater causing sooting, poor combustion and/or unsatisfactory heater performance.

Ratings specified by manufacturers for most appliances apply for elevations up to 2000 feet (610m). For elevations above 2000 feet (610), ratings must be reduced at the rate of 4% for each 1000 feet (305m) above sea level. For example, if a heater is rated at 78,000 Btuh (22.9 Kwh) at sea level, to rate the heater at 4000 feet (1219m), you subtract 4 (once for each thousand feet) x.04 (4% input reduction) x 78,000 (original rating) from the original rating.

Therefore, to calculate the input rating at 4,000 feet (1219m): 4 x

.04 x 78,000 = 12,480 Btuh (3.7 Kwh), 78,000 (22.9 Kwh) - 12,480 (3.7 Kwh) = 65,520 Btuh (19.2 Kwh). At 6000 feet (1829m) the correct input rating should be 59,280 Btuh (17.4 Kwh).

High Altitude Installations

Fire and Explosion Hazard

Under no circumstances should the input exceed the rate shown on the water heater’s rating label.

Overfiring could result in fire or explosion.

Gas and carbon monoxide detectors are available.

Natural Gas Installations

The natural gas fired version of the water heater covered by this manual is certified for use without modification for altitudes up to 10,100 feet.

For installations above 10,100 feet call the technical support phone number listed on the back cover of this manual for further technical assistance. Call the local gas or utility company to verify Btu per cubic foot content before calling for technical assistance and have that information available.

Note: The actual firing rate of the water heater must not exceed the input rating on the water heater's rating label under any circumstances.

Note: Due to the input rating reduction at high altitudes, the output rating of the appliance is also reduced and should be compensated for in the sizing of the equipment for applications.
