Vermont Castings Pinnacle & Stardance Direct Vent - Rear Vent Gas Heaters

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. Measure rear clearances from the outermost surface of the steel rear skirt.

The PDV20 and SDVR heaters are approved for installation into an alcove constructed of combustible materials to the dimensions and clearances shown on the next page.

The same clearances apply in a standard parallel installation.

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. Maintain a 2” (51mm) clearance 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 included with the venting system for complete installation procedures.
