PREINSTALLATION
1. PREINSTALLATION
Read carefully, study these instructions before beginning work.
This boiler must be installed by a qualified contractor.
The boiler warranty can be voided if the boiler is not installed, maintained and serviced correctly.
NOTICE
The equipment must be installed in accordance with those installation requirements of the authority having jurisdiction or, in the absence of such requirements, to the current edition of the National Fuel Gas Code, ANSI Z223.1/NFPA 54 and/or CAN/CSA B149.1, Natural Gas and Propane Installation Code.
Where required by the authority having jurisdiction, the installation must conform to American Society of Mechanical Engineers Safety Code for Controls and Safety Devices for Automatically Fired Boilers, ASME
A.ACCESSIBILITY CLEARANCES
Install boiler not less than 24″ (610 mm) between the left side, top, and front of the boiler and adjacent wall or other appliance, when access is required for servicing.
B.CLEARANCE FROM COMBUSTIBLE CONSTRUCTION
The design of this boiler is certified for alcove installation with the following clearances:
1.6″ (152 mm) between sides and combustible construction.
2.24″ (610 mm) between top of jacket and combustible construction.
3.6″ (152 mm) between draft hood and combustible construction.
4.6″ (152 mm) between vent pipe and combustible construction.
5.10″ (254 mm) between rear of jacket and combustible construction.
WARNING
Do not install this boiler on combustible flooring unless it is installed on a special combustible floor pan provided by PB Heat, LLC. Boiler installation on combustible flooring without the special pan is a fire hazard.
To order combustible floor pan, use the
WARNING
Do not install this boiler on carpeting. Boiler installation on carpeting is a fire hazard. Install this boiler on
C.AIR FOR COMBUSTION AND VENTILATION
1.Adequate combustion air and ventilation air must be provided for this appliance in accordance with the section of the National Fuel Gas Code entitled, “Air for Combustion and Ventilation” or applicable provisions of the local building code. Subsections 2 through 8 as follows are based on the National Fuel Gas Code requirements.
2.Required Combustion Air Volume: The total required volume of indoor air is to be the sum of the required volumes for all appliances located within the space.
Rooms communicating directly with the space in which the appliances are installed and through combustion air openings sized as indicated in Subsection 3 are considered part of the required volume. The required volume of indoor air is to be determined by one of two methods.
a.Standard Method: The minimum required volume of indoor air (room volume) shall be 50 cubic feet per 1000 BTU/Hr (4.8 m3/kW). This method is to be used if the air infiltration rate is unknown or if the rate of air infiltration is known to be greater than 0.6 air changes per hour. As an option, this method may be used if the air infiltration rate is known to be between 0.6 and 0.4 air changes per hour. If the air infiltration rate is known to be below 0.4 then the Known Air Infiltration Rate Method must be used. If the building in which this appliance is to be installed is unusually tight, PB Heat recommends that the air infiltration rate be determined.
b.Known Air Infiltration Rate Method: Where the air infiltration rate of a structure is known, the minimum required volume of indoor air for appliances other than fan assisted and for the Series MI Boiler shall be determined as follows:
