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
•Refer to the manufacturer's instructions included with the venting system for complete installation procedures.
