WARNING

1.Flammable materials, gasoline, pressurized containers, or any other items or articles that are potentially fire hazards must never be placed on or adjacent to the heater. The appliance area must be kept free of all combustible materials, gasoline and other flammable vapors and liquids.

2.Do not obstruct the flow of combustion and ventilation air to the appliance.

CLEARANCES

This heather is designed certified for installation on a combustible wall, in an alcove with minimum clearances to combustible construction of 51mm (2 inches) from sides, 305mm (12 inches) from top and bottom. A minimum of 305mm (12 inches) shall be allowed for maintenance of serviceable parts. Clearance from vent is dependent upon the clearance rating of the venting material used; that is type B-1 vent is approved for 1 inch clearance, B-2 vent for 2 inch, etc.

MOUNTING

The W125K…is designed certified for mounting to a wall. The heather must not be installed directly on a carpeted wall.

The heather must be mounted to the wall using appropriate anchoring materials, through the four holes provided.

Expansion and contraction of piping due to changing water temperature in pipes imparts movement to heater which, if mounted directly to a brittle, board such as plasterboard can cause failure of mounting.

Heater must be mounted level to assure proper operation.

VENTING

The BOSCH model W125K… instantaneous gas water heater has a built-in a draft diverter is designed for indoor installation only. The draft diverter outlet must be connected to a clear, unobstructed vent of the same size or larger, refer to:

-In Canada, CAN 1-B149 Installation Code for detailed requirements

-In U.S., ANZI Z223.I/NFPA 54 National Fuel Gas Code for detailed requirements

-The minimum length of a vertical vent up to the terminal must be 2 ½ feet.

WATER CONNECTIONS

The W125K comes supplied with a ½’’ NPT cold water inlet adapter and a flexible wire braid hot water outlet with a ½’’ NPT connection.

RELIEF VALVE

The listed pressure relief valve supplied must be installed near the hot water outlet at time of installation of the heater. No valve is to be placed between the relief valve and the heater. A drain line must be connected to the relief valve to direct discharge to a safe location. Do not install reducing coupling or any other restriction in the discharge line. The discharge line must be installed so as to allow complete

drainage of both the valve and the line.

GAS CONNECTIONS

Before connecting the gas supply to the heater check heater’s model/rating plate to make sure that gas on which heater is to operate is the same as specified on the model/ rating plate.

The W125K…instantaneous gas water heater is supplied with a gas pipe, a gas pressure regulator and a manual gas cock that must be installed on the heater before attaching the gas supply line, see figure 3. Failure to install gas pipe, the main manual gas valve and the pressure regulator, or the failure to install them in the sequence show in figure 3 will be in violation of the A.G.A. and C.G.A. certification of the unit and can cause damage to heat changer.

BOSCH water heaters are shipped from the factory with the gas pressure regulators preset for the gas shown on the rating plate to the correct pressure.

-In Canada, for high altitude operation;

-In U.S., for standard altitude operation unless specially

marked as a high altitude unit.
