Vent Requirements; Altitude Considerations - Lopi Burner Owner's Manual

12

Vent Requirements

• 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. Each direct vent
gas appliance must use it's own separate vent system.

In addition to the requirements listed here, follow the requirements provided with the vent.

When the vent passes through a wall a wall thimble is required. When the vent passes through a
ceiling a support box or firestop is required. When the vent passes through the roof, a roof flashing
and storm collar are required. Follow the instructions provided with the vent for installing these items.
NOTE: Wall thimbles may have different dimensions than what is required by this heater.
• The vent must maintain the required 1" clearance to combustible materials to prevent a fire. Do not
fill air spaces with insulation.

Altitude Considerations

• Failure to adjust the air shutter properly
may lead to improper combustion
which can create a safety hazard.
Consult your dealer or installer if you
suspect an improperly adjusted air
shutter.
This heater has been tested at
•
altitudes ranging from sea level to
6,000 feet (1,800 M). In this
testing we have found that the
heater, with its standard orifice,
burns correctly with just an air
shutter adjustment.
Approved Vent

Use 6-5/8" (168mm) diameter Simpson Dura-Vent Direct-Vent Pro (or GS)*.
* Other vent may be approved with this stove. Check with the vent manufacturer for details.

Always use the high-wind cap (or high-wind sconce cap, part # 46DVA-HSCH).

Vent Installation
• Slide the vent sections together and turn 1/4 turn until the sections lock in place.
• Screws are not required to secure the vent. However, three screws may be used to
secure vent sections together if desired.
• High temperature sealant is recommended at the appliance starter section connection
(use high-temperature silicone or Mill-Pac®).
• If disassembly is required, at time of re-assembly check to see if the vent creates a tight
fit. If it does not, apply high temperature sealant to the joints of the affected sections.
• Horizontal sections require a 1/4" rise every 12" of travel
• Horizontal sections require non-combustible support every three feet (e.g.: plumbing tape)
