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 closet installation
with the following clearances:
1. 6″ (152 mm) between sides, rear and front and
combustible construction.
2. 24″ (610 mm)between top of jacket and
combustible construction.
3. 2″ (51 mm) between vent pipe and combustible
construction.
C. AIR FOR COMBUSTION AND
VENTILATION
1. Adequate combustion air and ventilation air must be
provided in accordance with section 5.3, Air for
Combustion and Ventilation, of the National Fuel
Gas Code, ANSI Z223.1/NFPA 54, or Sections 7.2,
7.3 or 7.4 of CAN/CSA B149.1, Natural Gas and
Propane Installation Code or applicable provisions of
the local building code. Subsections 2 through 8 as
follows are based on the National Fuel Gas Code
requirements.
2. Requir
ed 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, we recommend 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 the
Series DE Boiler and other fan assisted
appliances shall be determined as follows:

, 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,
ANSI/ASME CSD-1.
NOTICE
Do not install this boiler on carpeting. Boiler
installation on carpeting is a fire hazard. Install this
boiler on non-combustible flooring or use a
combustible floor pan to install this boiler on other
non-carpeted flooring.
DANGER
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
