Dutchwest Natural Vent Gas Heater
30002008
Clearance Requirements
Minimum Clearances to Combustible
Materials
Measure side clearances as shown in Figures 2
through 5 from the outer edge of the cast iron stove
top. Measure rear clearances from the outermost
surface of the sheet metal rear skirt.
The Dutchwest heater is approved for installation into
an alcove constructed of combustible materials to the
dimensions and clearances shown in Figure 5.
The same clearances apply in a standard parallel
installation.
Hearth Requirements
The Dutchwest Heater must be installed on rigid
flooring. When the heater is installed directly on any
combustible surface other than wood flooring, a metal
or wood panel extending the full width and depth of the
unit must be used as the hearth. There are no other
hearth requirements.
WARNING:
•
Always maintain required
clearances (air spaces) to nearby
combustibles to prevent fire hazard. Do not
fill air spaces with insulation. All venting
components must maintain a 1" (25mm)
clearance to combustible materials. Maintain
a 6” (150mm) clearance when using single
wall pipe.
•
The gas appliance and vent system must be
vented directly to the outside of the building
and never be attached to a chimney serving a
separate solid fuel or gas-burning appliance.
•
Refer to the manufacturer's instructions
included with the venting system for
complete installation procedures.
