Dunkirk Q95M-200 Modulating Condensing Boiler - Manual (Page 6)

5.2 Boiler Sizing
• Verify you have selected boiler with proper capacity
before continuing installation. AHRI Rating of selected
boiler should be greater than or equal to calculated
peak heating load (heat loss) for the building or area(s)
served by boiler and associated hot water heating
systems. See Sea Level Ratings - Natural and Propane
Gases” Section 4.
• Heat loss calculations should be based on approved
industry methods.
5.3 Considerations for Boiler Location
Before selecting boiler location consider following.
• Supplied with correct type of gas (natural gas or
propane).
• Connected to suitable combustion air intake piping
system to supply correct amounts of fresh (outdoor) air
for combustion (15’ minimum equivalent length/100’
maximum equivalent length).
• Connected to suitable venting system. (15’ minimum
equivalent length/100’ maximum equivalent length).
• Connected to suitable hot water heating system.
• Supplied with suitable electrical supply for all boiler
motors and controls.
• Connected to properly located thermostat or operating
control (not included with boiler).
WARNING
Fire hazard. Do not install on carpeting. Failure to
follow these instructions could result in death or

!
• Placed on level surface (must NOT be installed on
carpeting).
• Pitch condensate drain line down to floor drain or
external condensate pump with reservoir at ¼” per foot
(wood frame or blocks may be used to raise boiler).
5.1 Before Boiler Installation
1.
Boiler is equipped for residential installations. If
used for commercial applications, additional code
requirements must be adhered to for installation. This
may require additional controls including but not limited
to a low water cut off, a manual reset high temperature
limit, and wiring and/or piping modifications.
2. Never vent products of combustion from this boiler to
enclosed space. Always vent to outdoors. Never vent to
another room or to inside building.
3. Keep boiler area clean of debris and free of combustible
and flammable materials.
4. Proper through wall or through roof combustion venting
shall be in accordance with materials and methods
