SECTION 2: Planning
The following codes and instructions should be followed when
planning the installation of the Heatstar ERSP 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.
Aircraft Hangers:
Installation in aircraft hangers must be in accordance with
the Standard for Aircraft Hangers, ANSI / NFPA-409 – latest
revision.
• Heaters in aircraft storage or service areas shall be installed
at a height of 10 feet above the upper surface of wings
or engine enclosures of the highest aircraft which may be
housed in the hanger. (This should be measured from the
bottom of the heater to the wing or engine enclosure,
whichever is highest from the floor.)
• In other sections of aircraft hangers, such as shops or offices,
heaters must not be installed less than 8 feet above the
floor.
• Heaters installed in aircraft hangers shall be located so as
not to be subject to damage by aircraft, cranes, moveable
scaffolding or other objects.
Public Garages:
Installations in garages must be made in accordance with the
Standard for Parking Structures, NFPA-88A – latest revision
or the Standard for Repair Garages, NFPA-88B – latest
revision.
• Heaters must not be installed less than 8 feet above
the floor. Minimum clearances to combustibles must be
maintained from vehicles parked below the heater.
• When installed over hoists, minimum clearances to
combustibles must be maintained from the uppermost point
on the hoist.
Venting:
The venting must be installed in accordance with NFPA-54 /
ANSI Z223.1 or CSA 149.1– latest revision, National Fuel Gas
Code. Partial information with regard to this code is provided
in (Section 5) of this installation manual with regard to size
and configurations for venting arrangements.
• Any portion of flue pipe passing through a combustible wall
must be dual insulated or have an approved thimble. Refer to
ANSI-Z223.1 or CSA149.1– latest revision.

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
Heatstar ERSP 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.
• 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.
