COMBUSTIBLE CONSTRUCTION CLEARANCES The water heater should be positioned to provide the minimum clearances from combustible surfaces and toprovide sufficient space for servicing the unit as follows. MINIMUM CLEARANCES: PROTECTED SURFACES Clearances to surfaces installedin rooms which are large (2) ...

COMBUSTION AND VENTILATION AIR SUPPLYCAUTION: Combustion air must not be contaminated by corrosive chemical fumes which can damage the heater and void the warranty. IMPORTANT: Adequate air must be provided for proper combustion and ventilation of the surrounding area. An inadequate supply of combust...

CAUTION: The heater and its manual shut off valve must be disconnected from the gas supply during any pressure testing of that system at test pressures in excess of 1/2 psig (3.45 KPA). Dissipate test pressure in the gas supplyline before reconnecting the heater and its manual shut off valve to gas ...

HOT WATER SUPPLY HEATER Model 136- 1826The heater is direct fired and used with a storage tank. The model number indicates the BTU/holds input. (i.e. an1826 holds input of 1,826,000 BTU/ HR)See specification and dimension information on pages 4, 5 and 6. TANK TEMPERATURE CONTROL 1. The tank temperat...

SEQUENCE OF OPERATION 1. Power to heater and recirculation pump.2. Control switch, located on heater control box, placed in "ON" position. a. High limit controller circuit closed.b. Tank temperature controller calls for heat.c. Pump relay energized starting heater pump.d. Flow switch activat...

Six Months:1. Heat Exchanger Surfaces. a. Shut off electric and gas supply to heater. b. Examine external surfaces 2. Preliminary examination maybe done by using amirror and a light in the burner area. 3. Remove venting, heater jacket top, flue collector andheat exchanger baffles. Remove inspection ...

2. Venting System Inspection Visually inspect the venting system. Make sure the vent connections are secure and have not becomedisengaged. Look for any indication of corrosion, orcarbon (soot) streaks which could cause leakage ofproducts of combustion into the living space. Inspect thevent terminal ...
