Altitude Considerations; Approved Caps - Lopi Northfield MV Owner's Manual

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 its 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.
Drafting Performance
This direct vent appliance requires natural draft to operate (similar to a wood stove or other heating appliance).
Draft can be adjusted using the included restrictor. The restrictor settings detailed in the manual should be
followed (variations may occur depending upon installation parameters).
Many factors may negatively influence the draft of the appliance. Travis Industries will not be responsible for
improper draft due to factors such as trees, hills, buildings, obstructions, excessive wind, extreme hot or cold
outdoor temperatures, restrictive vent terminations, or influence from mechanical systems.
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 4500 feet (1,372 M). In this
testing we have found that the
heater, with its standard orifice,
burns correctly with just an air
shutter adjustment.

Approved Caps


Always use the high-wind cap
(the sconce cap is not
