UIDELINES
LPG Appliances subject to gas supply authority inspection.
The building structure should be able to carry the operating weight of unit, all relevant stands and
ductwork, as well as service and installation personnel.
Keep unit clear of any heating flues, kitchen exhaust, toilet exhaust, sewerage vent pipes etc. Keep ample
clearance on all air inlet sides of unit. A basic rule is not less than 1 meter. Do not site the unit over or
near a skylight. Installation or service personnel could fall through causing damage and injury. Roof stand
kits are available for all models. Ensure that stand is fitted such that the unit remains level.
When slinging any unit for a crane lift, ensure that an adequate sized rope sling is used. The sling should
be wrapped round the bottom of the unit. DO NOT tie slings around and under the roof (top) panel or
through the fan housing. It is advisable when slinging unit to use a bar or wooden spreader laid across the
top of the unit protruding past edges sufficient to stop damage to paint or roof panel.
NOTE: Base panel lifting frames with hooks or eye holes are standard on all sizes of HCV unit.
Consult local building codes for any special requirements. For example: water supply, gas supply, electrical
supply and building structural computations.
Electricity Supply: All electrical connections and wiring must conform to AS3000 and be in
accordance with local requirements.
Flue: Material and installation shall comply with A.G.A Code 5601 (Installation code for Gas
Burning Appliances and Equipment).
Gas Supply: A gas supply line of adequate size shall be connected to the heater. Refer AS 5601
pipe sizing chart.
Water Supply: All water connections and piping must conform to standard codes and local
requirements.
Do not locate unit in an enclosed plant room unless sufficient openings are available to ensure air pressure
in the plant room cannot become negative with all items in the plant room operating. For installations
similar to this, consult fuel supply authority prior to installing. Temperature rise on ”HEAT” must be within
the range of 11°C to 33°C on full flame. Overheating due to incorrect damper setting or restrictive
ductwork may cause problems with heating operation, causing high limit safety control to activate. Gas
burner pressure must be set as per data plate. Firing rate cannot be increase beyond data plate rating. As
part of installation procedure, units must be set up and tested by authorised installer.

NSTALLATION
The following recommendations are not intended to supplant or take precedence over relevant official
regulations.
On receipt of equipment
a)
Inspect the unit for any damage caused in transit. Any such damage must be immediately reported
to the shipper of the goods.
b)
The unit has been factory tested to check for correct operation of all components. If any part is
obviously missing or damaged, notify the supplier immediately.
c)
Check the appliance to ensure that the H.C.V has been supplied for the correct supply, ie Natural,
Towns or LPG gas.
Unit Location
a)
The H.C.V is designed essentially as a roof top or external ground mount unit, however, under
certain conditions it can be located in a plant room if positive pressure is maintained by mechanical
ventilation or the heater section is isolated from the cooler section within the plantroom. This
equipment is not designed for long and complex air distribution ductwork and as such the H.C.V
should be located as close as practicable to the points of air distribution. Depending on large
