D. High Altitude Installations
U.L.Listedgasappliancesaretestedandapprovedwithout
requiring changes for elevations from 0 to 2000 feet in the
U.S.A. and Canada.
When installing this appliance at an elevation above 2000
feet, it may be necessary to decrease the input rating by
changing the existing burner orifice to a smaller size. Input
rate should be reduced by 4% for each 1000 feet above
a 2000 foot elevation in the U.S.A., or 10% for elevations
between 2000 and 4500 feet in Canada. If the heating
value of the gas has been reduced, these rules do not
apply. To identify the proper orifice size, check with the
local gas utility.
If installing this appliance at an elevation above 4500 feet
(in Canada), check with local authorities.
Do NOT use this appliance if any part has been under water.
Immediately call a qualified service technician to inspect the
appliance and to replace any part of the control system and
any gas control which has been under water.
E. Non-Combustible Materials Specification

those consisting entirely of steel, iron, brick, tile, concrete,
slate, glass or plasters, or any combination thereof.
Materials that are reported as passing ASTM E 136,
Standard Test Method for Behavior of Materials in a
Vertical Tube Furnace at 750oC, shall be considered
non-combustible materials.
F. Combustible Materials Specification

A. Design and Installation Considerations
Heat & Glo B-type vent gas appliances are designed to
operate with all exhaust gases expelled to the outside of
the building, and combustion air pulled from the room.
Getting Started
2
When planning an appliance installation, it’s necessary to
determine the following information before installing:
•Where the appliance is to be installed. See Sections 3
and 4.
•Theventsystem configuration to be used. See Sections
5 and 6.
•Gas supply piping. See Sections 7 and 9.
•Electrical wiring. See Sections 7 and 10.
•Framing and finishing details. See Sections 3, 6 and 11.
•Whetheroptionalaccessories—devicessuchasafan,wall
switch, or remote control—are desired. See Section 10.
Check building codes prior to installation.
• Installation MUST comply with local, regional, state and
national codes and regulations.
• Consult local building, fire officials or authorities having
jurisdictionabout restrictions,installation inspection,and
permits.
CAUTION

B. Negative Pressure
Draft is the pressure difference needed to vent fireplaces
successfully. Considerations for successful draft include:
• Preventing negative pressure
• Location of fireplace and chimney
Negative pressure results from the imbalanceofair avail-
able for the fireplace to operate properly. Causes for this
imbalance include:
• Exhaust fans (kitchen, bath, etc.)
• Range hoods
• Combustionairrequirements for furnaces, waterheaters
and other combustion appliances
• Clothes dryers
• Location of return-air to furnace or air conditioning
• Imbalances of the HVAC air handling system
• Upper level air leaks (recessed lighting, attic hatch
opening, duct leaks)
To minimizetheeffectsof negativeair pressure,thefollow-
ing must be considered:
• Install the fresh air kit. Install the intake on the side of
the house towards prevailing winds during the heating
season.
• Ensureadequateoutdoor air is supplied for combustion
appliances and exhaust equipment.
• Ensurefurnaceandairconditioning return vents are not
located in the immediate vicinity of the fireplace.
• Avoid installing the fireplace near doors, walkways or
small isolated spaces.
• Recessedlightingshouldbe of “sealed can”design;attic
hatches weather stripped or sealed; and attic mounted
ductwork and air handler joints and seams taped or
sealed.
• Basement installations should be avoided due to stack
effect. Stack effect creates negative pressure in lower
levels. Hearth & Home Technologies recommends the
use of direct vent fireplaces in basements.
Location of the fireplace and chimney will affect perfor-
mance. As shown in Figure 2.1, the chimney should:
• Be installed through the warm space enclosed by the
building envelope. This helps to produce more draft,
especially during lighting and die-down of the fire.
• Penetrate the highest part of the roof. This minimizes
the effects of wind turbulence.
• Belocatedaway from trees, adjacentstructures,uneven
roof lines and other obstructions.
Offsets can restrict draft so their use should be minimized.
Consider the fireplace location relative to floor and ceiling
and attic joists.
Asphyxiation Risk.
• Negative pressure can cause spillage of
combustion fumes and soot.
• Fireplace needs to draft properly for safety.

in any manner.
Walls, ceiling, base plate and cantilever floor of the chase
should be insulated. Vapor and air infiltration barriers
should be installed in the chase as per regional codes for
the rest of the home. Additionally, in regions where cold
air infiltration may be an issue, the inside surfaces may be
sheetrocked and taped for maximum air tightness.
To further prevent drafts in cold climates, the firestops
shouldbecaulked with hightemperaturecaulktosealgaps.
Gas line holes and other openings should be caulked with
high temp caulk or stuffed with unfaced insulation. If the
appliance is being installed on a cement slab, a layer of
plywood may be placed underneath to prevent conducting
cold up into the room.

feet in the U.S.A. and Canada.
When installing this appliance at an elevation above
2000 feet, it may be necessary to decrease the input
rating by changing the existing burner orifice to a
smaller size. Input rate should be reduced by 4% for
each 1000 feet above a 2000 foot elevation in the
U.S.A., or 10% for elevations between 2000 and 4500
feetinCanada. If the heatingvalue ofthe gashasbeen
reduced,theserulesdonot apply.To identify the proper
orifice size, check with the local gas utility.
If installing this appliance at an elevation above 4500
feet (in Canada), check with local authorities.
• Ensure that gas line does not come in contact with outer
wrap of appliance. Follow local codes.
• Incoming gas line should be piped into the valve com-
partment and connected to the 1/2 inch connection on
the manual shutoff valve.
