HeatStar COMFORTER Serie Instrucciones De Operacion Y Manual Del Propietario página 3

SECTION 2: Planning
The following codes and instructions should be followed when
planning the installation of the Heatstar AG heater. In addition to
these instructions, the warnings in (Section 1) must be carefully
adhered to since improper installation may lead to property damage,
injury, or death.
National Standards and Applicable
Codes
Gas Codes:
The type of gas appearing on the nameplate must be the
type of gas used. Installation must comply with local codes
and recommendations of the local gas company, and the
National Fuel Gas Code, ANSI Z223.1 – latest revision,
(same as NFPA Bulletin 54) or the Natural Gas and Propane
Installation Code, CSA B149.1.
• Clearance between the heater and its vent and adjacent
combustible material (which is part of the building or its
contents) shall be maintained to conform with the Standard
for Installation of Gas Appliances and Gas Piping, NFPA-54 /
ANSI Z223.1 – latest revision, National Fuel Gas Code or the
Natural Gas and Propane Installation Code, CSA B149.1.

Hazardous Locations:
Where there is the possibility of exposure to combustible
airborne material or vapor, consult the local Fire Marshal, the
fire insurance carrier or other authorities for approval of the
proposed installation.
Critical Considerations
COMFORTER is a suspended heater. Therefore, its stability,
flexibility, and safety are very important. Before starting
installation, be sure the system can meet the following
requirements.
• For either indoor or outdoor installation. Not for use in resi-
dential dwellings.
• Maintain specified clearances to combustibles, and safe dis-
tance from the heat-sensitive material, equipment and work
stations.
• The stated clearances to combustibles represent a surface
temperature of 90°F (30°C) above room temperature.
Building materials with low heat tolerance (such as plastic,
vinyl siding, canvas, etc.) may be subject to degradation at
lower temperatures. It is the installers responsibility to assure
that adjacent materials are protected from degradation.
• Provide a suspension with vertical length of chain or swinging
rod which has at least 2 inches of horizontal travel for each
burner in a straight run. Be sure the suspension system is
sufficiently flexible to accommodate thermal expansion which
occurs as the system heats up (see Figure 6 on page 12).
• Provide access to burners for servicing, preferable on both
sides, above and behind the burner for removal.
• Provide a minimum of 18 inches of clearance between burn-
ers and building walls. (Always observe minimum clearances
to combustibles.)
• Be sure the heater has a downward pitch of one-half inch per
20 feet away from the burner. (1.25 cm per 6.1 m)
• Provide signs in storage areas to specify maximum stacking
height to maintain required clearances to combustibles, and
these signs must either be posted adjacent to the heater
thermostats or in the absence of such thermostats in a
conspicuous location.
• Plan location supports (see Figure 2A-G starting on page 8).
Locate a support near all elbows.
• The installation must conform with local building codes or
in the absence of local codes, with the National Fuel Gas
Code, ANSI Z223.1/NFPA 54 or the Natural Gas and Pro-
pane Installation Code, CSA B149.1.
• If an external electrical source is utilized, the heater, when
installed, must be electrically grounded in accordance with
the National Electrical Code, ANSI/ NFPA 70 or current
Canadian Electrical Code, CSA C22.1.
