Welcome to the new range of powered infra-red
heaters. Local regulations may vary and it is the
installer’s responsibility to ensure that such
regulations are satisfied.
All installation, assembly, commissioning and
service procedures must be carried out by
suitable qualified competent persons and
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

1.1 H eal th a nd Sa f e t y
A. Heater is intended for heating
non-residential indoor spaces and should
only be installed where flammable gases or
vapors are not generally present.
B. Heaters may be suspended either horizontal
or at any angle. See section 1.3 for
clearance dimensions.
C. The installation must conform with local
building codes or, in the absence of local

pane In s ta ll at i on C ode, C SA B149.1 , and
are so marked.
Ensure that minimum clearances will be
maintained to vehicles parked below the
heater.
F . The standard heaters are approved for
installations between 0 - 2000ft (0 - 610m)
for the US and 0 - 4500 ft (1370m) for
Canada. Conversion kits are available on
installations above these heights in the
USA.
1.2 H ea t e r S u s p e n si on
Attachment to the heater support lugs should
be made by D shackle. The hanging
attachments to overhead steelwork etc. must
be purpose made to sound engineering
practice or supplied by others.
They must be adequately fixed and designed
to carry the whole weight of the heater. In the
event of suitable roof steelwork being
unavailable, additional steelwork should be fitted
to enable vertical hangers to be used for
suspending the heaters.
These methods are illustrated in Figure 1. If
there are any doubts as to the strength or
suitability of roof steelwork to which heaters are
to be suspended, please refer to a Consultant,
Architect or owner of the building.
It is recommended that the heater is raised to its
final position once the assembly of the tube/
bracket/reflector has been completed. Longer
tube assemblies may be raised in more than
one sub-assembly with final tube connection
made in the air.
The suggested mounting heights for heaters are
given in the chart next page.

1.4 Gas Conn ec t i on a nd S upp ly
The gas connection on the heater is ½” N.P.T
internal thread.
Injector sizes and manifold pressure for the
burners are shown in the table 4. The gas
supply piping and connections must be installed
so that the minimum pressure stated is
achieved.
A gas shut off valve and union should be fitted
in the gas supply line close to the heater and a
” N.P.T plugged tapping, accessible for test
gauge connection, provided immediately
upstream of the appliance gas inlet.
It is essential to provide some flexibility in the
final gas connection by use of an approved
flexible gas connector. See Fig 4.

Additional wiring is required to install an optional extra thermostat and / or time clock.
If no thermostat is required then a jumper is fitted between terminals R and W1. In this

1.6 Ve nt R e qu i re me nt s a nd D e t ails
1.6.1 Un ve nt e d un i t s
Heaters may be installed without a vent
providing the governing building codes are met
and consideration is properly given to
possibilities of condensation on cold surfaces.
Installation shall meet the following
requirements when unvented:
Natural or mechanical means shall be
provided to supply and exhaust at least 4
CFM per 1000 BTU per hour input of
installed heaters.
Combustion gasses shall not impinge on
combustible materials.
1.6.2 Ve r t ical ve nt i ng
The heater can be installed with a vertical vent.
All vent piping should be adequately supported
from the building structure and terminated with
an approved terminal. Th e maxim u m
rec
o mme nd e d ve nt le ngth is 25 ft ( 7.6m ) wi th
a maxim u m of t w o el bo ws . All connections
should be properly sealed. Refer to fig 7a.
1.6.3 Ho ri zont al ve nt i ng
Individual units can be vented horizontally
through side walls. Recommended terminals
are Part Numbers V0700 for 4” and V0800 for
6”.
Distances from adjacent public walkways,
adjacent buildings, openable windows and
building openings, consistent with the N
at i ona l
F
ue l Ga s C ode, A N SI Z 223.1/ NF PA 54 or the
N
atu r a l Ga s and P r opane In s ta ll at i on C ode,
C SA B149.1.
Maximum length of vent is 25ft (7.6m) with two
- 90° elbows.
Runs of 12ft (3.6m) or shorter can use
4” (101mm) dia vent. Runs over 12ft (3.6m)
should use 6” (152mm) vent pipe.
Any portion of vent that passes through a
combustible wall must be insulated, or use an
approved insulating thimble.
Standard vent terminals must extend at least
6” (152mm) from the wall and at least
24” (609mm) from any combustible overhang.
This protects the building material from
degradation by the vent gasses.
Vent joints should be sealed and secured
according to the vent manufacturers
instructions. Should condensation occur the
vent should be shortened or insulated.
The terminal should be at least 3ft (0.91m) away
from any air intake to the building.
If the heater is equipped with ducted combustion
air, the vent terminal must be at least 3ft
(0.91m) away from the air inlet and located
higher than the inlet.
The vent terminal must be installed at a suitable
height above the ground to prevent blockage by
snow.
1.7 F res h A ir I nt ake
Whenever the heater is installed in locations
where airborne dust or other pollutants are
present, a fresh air supply should be ducted to
the burner.
A fresh air duct of 4”(101mm) dia. should be
installed from the fresh air to the air intake
connection on the fan housing. A flexible
jointing piece should be installed at the fan
connection with hose clamps to facilitate
expansion and contraction.
The maximum recommended length air duct is
25ft (7.6m) and the maximum number of elbows
is two. The minimum length is 18” (456mm).
The location of the fresh air duct inlet must be
where it will receive dust free clean air. An inlet
cap with bird screen must be fitted at the inlet of
the duct. If the duct inlet is located above the
roof the underside of the inlet terminal must be
at least 2ft (0.61m) above roof level and at least
10” (254mm) above any projection on the roof
within 7ft (2.1m) of the inlet. Intake pipe, fittings
and sealant are not furnished by the
manufacturer. Refer fig 7c & d.

shown on the drawings are adjacent to the
burner and secures the first suspension bracket
to the tube with a tube strap. All other
suspension brackets ’G’ shown on the

After removing the protective plastic coating
(if fitted), slip the reflectors through the hanger
brackets until they overlap each other.
The first and second reflector are fixed at the
point F by a type F reflector support bracket and
are held in place by tightening the fixing screws.
Alternate fixings of further reflectors by type S
and type F reflector brackets and space as
indicated by individual assembly sheets.
