or rain during operation or service.

4.If the Munchkin Boiler is to replace an existing boiler, check for and correct any existing system problems such as:

•System leaks.

•Incorrectly-sized expansion tank.

•Lack of freeze protection in boiler water causing system and boiler to freeze and leak.

•Excessive glycol which will affect the boiler system operation.

D.CLEARANCES FOR SERVICE ACCESS

1.See Figure 3-1 for recommended service clearances. If you do not provide minimum clearances shown, it might not be possible to service the boiler without removing it from the space.

Figure 3-1: Clearances required

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 boiler. The boiler cover must be se- curely fastened to the boiler to prevent boiler from drawing air from inside the boiler room. This is particularly important if the boiler is lo- cated in the same room as other appliances. Failure to comply with the above warnings could result in severe personal injury, death or sub- stantial property damage.

E. RESIDENTIAL GARAGE INSTALLATION

Precautions

Take the following special precautions when installing the boiler in a residential garage. If the boiler is located in a residential garage, per ANSI Z223.1, paragraph 5.1.9:

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

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

F.EXHAUST VENT AND INTAKE AIR VENT

The Munchkin Boiler requires a special vent sys- tem, designed for pressurized venting. Munchkin Boilers are rated ANSI Z21.13 Category IV (pressurized vent, likely to con- dense in the vent).

You must also install air intake piping from out- side to the boiler flue adaptor. The resultant installation is categorized as direct vent (sealed combustion). Note: To prevent combustion air contamination 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 Boiler using any other means. Be sure to locate the boiler such that the air intake and exhaust
