Clearance Requirements

Minimum Clearances to Combustible Materials
Measure side clearances as shown in Figures 3, 4 and
5 from the outer edge of the cast iron stove top. Mea-
sure rear clearances from the outermost surface of the
steel rear skirt.
The PDV20 and SDVR heaters are approved for instal-
lation into an alcove constructed of combustible materi-
als to the dimensions and clearances shown on the

The same clearances apply in a standard parallel instal-
lation.

Pinnacle & Stardance Direct Vent - Rear Vent Gas Heaters
• 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 combus-
tible materials. Maintain a 6" (152mm) clear-
ance when using single wall pipe. Maintain a
2" (51mm) clearance on top and 1" (25 mm) on
sides and bottom when venting straight off the
rear.
• 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 in-
cluded with the venting system for complete
installation procedures.
