GAS-FIRED BOILER Boiler Manual

PART 3: PREPARE BOILER LOCATION (CONTINUED)

vent piping can be routed through the building and properly terminated. The air intake and exhaust vent piping lengths, routing and termi- nation method must all comply with the methods and limits given in the Venting section.

G. PREVENT COMBUSTION AIR CONTAMINATION

Install intake air piping for the Munchkin Boiler as described in the Venting section. Do not ter- minate exhaust in locations that can allow con- tamination of intake air.

H.WHEN REMOVING A BOILER FROM AN EXISTING COMMON VENT SYSTEM

DANGER

Do not install the Munchkin Boiler into a common vent with any other appliance. This will cause flue gas spillage or appliance malfunction, resulting in possible severe personal injury, death or substantial property damage.

WARNING

You must pipe outside air to the boiler air intake. Ensure that the intake air will not contain any of the contaminants below. Contaminated air will damage the boiler, 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.

WARNING

Failure to follow all instructions can result in flue gas spillage and carbon monoxide emissions, causing severe personal injury or death.

At the time of removal of an existing boiler, the following steps shall be followed with each appliance remaining connected to the common venting system placed in operation, while the other appliances remaining connected to the common venting system are not in operation.

a.Seal any unused openings in the common venting system.

b.Visually inspect the venting system for proper size and horizontal pitch and determine there is non blockage or restriction, leakage, corrosion and other deficiencies which could cause an unsafe condition.

c.Insofar as is practical, close all building doors and windows and all doors between the space in which the appliances remaining connected to the common venting system are located and other spaces of the building. Turn on clothes dryers and any appliance not connected to the common venting system. Turn on any exhaust fans, such as range hoods and bathroom exhausts, so they will operate at maximum speed. Do not operate a summer exhaust fan. Close fireplace dampers.

d.Place in operation the appliance being inspected. Follow the lighting instructions. Adjust thermostat so appliance will operate continuously.

e.Test for spillage at draft hood opening after 5
