Boiler Location - NTI WF200 Installation And Operation Manual

Installation and Operation Manual

3.0 BOILER LOCATION

In all cases, the WF200 boiler must be installed indoors in a dry location where the ambient temperature must be
maintained above freezing and below 100F [38C]. All boiler components must be protected from dripping,
spraying water, or rain during operation and servicing. Consider the proximity of system piping, electrical
supply and chimney termination when determining the best boiler location.
Water or flood damaged components must be replaced immediately with new factory-
approved components as failure to do so may result in fire, serious injury, or death.
Air for Combustion & Ventilation
Protection against depressurization – the WF200 boiler operates on natural draft, therefore the space containing
the boiler must not be susceptible to becoming depressurized. Follow the direction outlined in section 5.1.3 of
CAN/CSA B365, Installation code for solid-fuel-burning appliances and equipment, to determine if a makeup
air system is required.
A makeup air system need not be installed if a spillage detection and alarm system (e.g. a
carbon monoxide alarm) is installed in accordance with local regulations, or the National
Building Code.
Ventilation air supply in confined spaces – when installed in an enclosed space, with a volume less than 20% of
the space being heated by the wood fired boiler, the space shall:
a) have a permanent opening or openings for natural air circulation with a minimum net free area of 150 in
and
b) be connected to another space or spaces such that the total volume of air available for natural air
circulation is at least 30% of the total volume to be heated by the wood fired boiler.
The minimum dimension of any opening as specified in (a) above, shall be no less than 1
in. The lower edge of at least one opening shall be located within 1.5 ft of the floor of the
enclosed space, and the upper edge of at least one opening shall be located within 1.5 ft of
the ceiling of the enclosed space.
Clearance to Combustible Material
Place boiler on a non-combustible floor (see Foundation below), observe the minimum clearances to combustible
material listed in Table 3-1 and illustrated in Figure 3-1.
Failure to adhere to the installation clearances and restrictions detailed in these
instructions can lead to risk of fire or explosion resulting in property damage, personal
injury or death.
Foundation – The boiler should never be installed on a combustible floor or base. Foundations shall be installed
with the following minimum dimensions (see Figure 3-1):

4 in. thick

Extended 6 in. beyond the boiler sides and back.

Extend 18 in. in front of the boiler
Wood Storage – Maintain a minimum clearance of 5 ft. between the wood boiler and a
woodpile; the space around the boiler should be kept clean and free of litter and wood
residues. Where fans are used in the wood storage area, they should be installed so as not
to create negative pressures in the room where the wood boiler is located.
