Do not store or use gasoline or other flammable vapours and liquids in the vicinity
of this or any other gas fired appliance.
It is recommended that a full heating design including heat loss calculation be conducted on
the structure or area to be heated. Heater sizing and placement must consider available
mounting height, sources of greatest heat loss, and the certified clearances to combustibles
with respect to stored material, moveable objects (cranes, vehicles, lifts, overhead doors, etc),
sprinkler system heads, and other obstructions on the site. Consideration must also be given to
vent / duct placement and the allowable combined lengths of vent and duct. Carefully survey
the area to be heated, and for best results place burner and combustion chamber in the coldest
area(s) .
Installation must conform with all local, state, provincial and national code requirements includ-
ing the current latest edition ANSI Z223.1 (NFPA 54) in the U.S.A. and B149.1 installation
code in Canada, for gas burning appliances and equipment. The latest edition Electrical Code
ANSI/NFPA N0 70 in the U.S.A. and PART 1 CSA C22.1 in Canada must also be observed.

This heater must be mounted with at least the minimum clearances between the heater and
combustibles as shown in FIG-1, TABLE 1, Page 7. It is the installer’s responsibility to ensure
that building materials with a low heat tolerance which may degrade at lower temperatures are
protected to prevent degradation. Examples of low heat tolerance materials include vinyl sid-
ing, fabrics, some plastics, filmy materials, etc.
Positioning of lights, sprinkler heads, overhead doors, storage areas, gas and electrical lines,
parked vehicles, cranes and any other possible obstruction or hazard must be evaluated prior
to installation.
: The lower ‘jaw’ of the burner cabinet swings down to provide
convenient service access to burner components. Provide a minimum clearance from any wall
or obstruction of 6 inches (15 cm) to the access end of the burner housing, and a minimum of
24 inches (61 cm) to any ONE side to allow servicing of burner, blower and controls. (see Fig-
ure 2 below) - the minimum clearances to combustibles must always be maintained.

* GUIDELINE MOUNTING HEIGHTS are typical to provide optimum comfort in general indoor-
space heating applications. Variance to these typical heights can occur in some applications:
• Higher mounting heights due to structure or application requirements
• Lower mounting heights for area or ‘spot’ heat indoor or , or in areas with greater infiltra-
tion losses (near overhead doors, etc)
: Single or multiple heater placement must be such that continuous
operation of heater(s) will not cause combustible material or materials in storage
to reach a temperature in excess of ambient temperature plus 90F° (50C°).

Inadequate or improper suspension of the tube heater can result in collapse of
the system, property damage, and personal injury or death.
It is the installer’s responsibility to ensure that the hardware and structural
supports from which the heater is suspended are sound and of adequate
strength to support the weight and expansion forces of the heater.
Consider that the heater will expand in length as much as 1/2 inch (12.5 mm) or more for every
10 ft (3 m) of system length – typically the greater the firing rate, the greater the expansion.
1) Survey the available structural supports, considering the system configuration and heat re-
quirements of the area to establish the optimum heater location.
a) Locating a heater directly under joists or beams, or installing supplemental steel support
rail or angle iron can substantially reduce labor and materials
2) Tube system hangers must be located: A) straight in line; B) at a common height (level);
and C) 116” (295 cm) apart.- see Figure 6 next page.
a) NOTE: It is important that the tubes in the system are installed in alignment horizontally
(level) and vertically (in line) – this will ensure system integrity
3) Hardware with a minimum 60 lb. (30 kg) work load must be used at each heater suspension
point. A #8 Jack Chain or equivalent is typically used for suspending the heater.
a) Connect to the structure using typical hardware as illustrated in FIGURE 5 (below) or by
other mechanically sound means
b) If rigid devices such as 3/8” threaded rods are used for suspension, swing joints or other
means must be provided to allow for system expansion - approximately ½ inch to 1 inch
for every 10 ft (1 cm to 2.5 cm for every 3 m) of system length.
4) Two types of hangers are provided to suspend the tube system – see FIGURES 6 & 7
a) Plate hangers support the tubes and reflectors at each end of the tube system
b) Webbed hangers support tubes and reflectors at each tube junction

In areas prone to earthquake, or as specified on a project, install lateral and longitudinal seis-
mic restraints as indicated in Figure 11. If the heater location can be impacted by wind (aircraft
hangars, etc) refer to High Wind Restraint section -.
These restraint systems indicate suspension of and attachment to the heater. The attachment
of suspension hardware to the structure will be as required by site structural conditions, instal-
lation codes, and/or local engineering design requirements. Other types or systems of restraint
may be specified by local or national codes, or by project engineering design specifications.
Schwank / InfraSave offers optional items: #2 Lion Chain 115 lb work load x 200 ft roll (PN: JL-
0800-XX); and Safety Snap Hooks (PN: JL-0800-SH = pkg 24; JL-0800-SH-B = pkg 100).
All other required seismic mounting hardware is field supplied by the installer.
- -
In areas with wind conditions (aircraft hangers, etc) in addition to lateral and longitudinal re-
straint the heater must be restrained from vertical movement. Suspend the heater using 3/8”
threaded rod with 3” adjustment turnbuckle through a safety ring at each hanger location.
