PART 3: PREPARE MUNCHKIN CONTENDER LOCATION (CONTINUED)

WARNING

The space must be provided with combus- tion/ventilation air openings correctly sized for all other appliances located in the same space as the Munchkin Contender heater. The heater cover must be securely fastened to the heater to prevent heater from drawing air from inside the heater room. This is particularly important if the heater is located in the same room as other ap- pliances. Failure to comply with the above warn- ings could result in severe personal injury, death or substantial property damage.

D. RESIDENTIAL GARAGE INSTALLATION

Precautions

Take the following special precautions when installing the Munchkin Contender in a residen- tial garage. If the heater is located in a residen- tial garage, per ANSI Z223.1, paragraph 5.1.9:

•Mount the heater with a minimum of 18 inches above the floor of the garage to the bottom of the heater to ensure the burner and ignition devices will be no less than 18 inches above the floor.

•Locate or protect the heater so it cannot be damaged by a moving vehicle.

E.EXHAUST VENT AND INTAKE AIR VENT

The Munchkin Contender requires a special vent system, designed for pressurized venting. Munchkin Contenders are rated ANSI Z21.10.3 Category IV (pressurized vent, likely to con- dense in the vent).

You must also install air intake piping from outside to the heater flue adaptor. The resultant installa- tion is categorized as direct vent (sealed combus- tion). Note: To prevent combustion air con- tamination see Table 3-2 in this section when considering exhaust vent and intake air vent termination.

Intake and exhaust must terminate near each other and may be vented vertically through the roof or out a side wall. The intake and exhuast venting methods are detailed in the Venting Section. Do not attempt to install the Munchkin Contender Heater using any other means. Be sure to locate the heater such that the air intake and exhaust vent piping can be routed through

the building and properly terminated. The air intake and exhaust vent piping lengths, routing and termination method must all comply with the methods and limits given in the Venting section.

F. PREVENT COMBUSTION AIR CONTAMINATION

Install intake air piping for the Munchkin Contender as described in the Venting section. Do not terminate exhaust in locations that can allow contamination of intake air.

WARNING

You must pipe outside air to the heater air intake. Ensure that the intake air will not contain any of the contaminants below. Contaminated air will damage the heater, resulting in possible severe personal injury, death or substantial property damage. For example, do not pipe intake air vent near a swimming pool. Also avoid areas subject to exhaust fumes from laundry facilities. These areas will always contain contaminants.
