Gas piping and pressures
All piping must be in accordance with
requirements outlined in the National Gas
Codes (different for each country). Gas supply
piping installation should also conform with
good practice and any local codes. Support
gas piping with pipe hangers, metal strapping,
or other suitable material. Do not rely on the
heater to support the gas pipe.
All sealing products shall be resistant to the
action of liquefied petroleum gas or any
other chemical constituents of the gas being
supplied.
Install a ground joint union and manual shut
off gas valve upstream of the unit control
system.
All components of a gas supply
system must be leak tested prior
to placing equipment in service.
NEVER TEST FOR LEAKS WITH AN OPEN
FLAME. Failure to comply could result
in personal injury, property damage or
death.
This appliance is equipped for a maximum
gas supply pressure of 50 mbar.
Pressure testing supply piping
Test pressures above 50 mbar : Disconnect the
heater and manual valve from the gas supply
line which is to be tested. Cap or plug the
supply line. Test pressures below 50 mbar :
Before testing, close the manual valve on the
heater. Leak test all connections by brushing
on a leak detecting solution.
Do not over tighten and do not
rotate the gas valve inside the
heater control compartment

Electrical connections
THIS APPLIANCE MUST BE
EARTHED.
The electrical installation may only be carried
out by an appropriately qualified person. The
supply line to the heater should include a
main switch. The minimum clearance distance
between the contacts must be more than
3 mm.
All electrical connections should be made in
the heater control compartment. Screw type
terminals are provided. Connections should be
in accordance with the terminal markings and
the wiring diagram affixed to the air heater.
Attention: Serious damage can occur to burner
relay when faulty connection of thermostat,
reset switch or burner failure lamp.
Switching of wires for reset switch and flame
failure (e.g.in a remote control box) will
destroy the burner relay.
The minimum external control required for
the air heater is a room thermostat. It is
essential that the main input line and neutral
to terminals L and N remain live at all times
even when the heater is switched off to ensure
correct operation of the unit.
A burner reset switch with red indicator light
is fitted on the heater. To add a remote reset
button, make connections to the terminals
in the electric box as indicated on the wiring
diagram
