3. INSTALLATION
Not withstanding their limited scope, the appliance should be installed in accordance with the relevant
provisions of any National Gas Safety (Installation and Use) Regulations. Due account should also be
taken of any obligations arising from any National Health and Safety at Work Regulations, National and
Local Building Regulations and National Electrical Wiring Regulations. The appliance must be installed,
and where necessary, converted for use on other gases, by a qualified installer.
3.1 Suspension
3.1.1 The appliance should be located with respect to building construction and other equipment to permit
access to the appliance for servicing etc.
3.1.2 For suspending the appliance it is recommended that suitable protected welded chain (Ø3mm x 65 links
per m) or Ø8mm min mild steel drop rods and suitable brackets are used. Attach the chains or drop rods
to the hanger brackets where shown (see section 4). Providing at least Ø5mm closed link hooks are used
chains may be attached directly to the hanger brackets.
3.1.3 The appliances may be mounted horizontally or at a recommended angle of 300maximum to the horizontal
as shown below.

Maximum supply pressure (Pmax) 25mbar
Minimum supply pressure (Pmin) 17mbar
Setting pressure 12.5mbar
Gas connection R - ½
3.2.1.1 Installation pipes should be fitted in accordance with National and Local Regulations. Pipes of a smaller
size than the heater connection (R - ½) should not be used and the pipe work must be designed to
achieve a gas supply pressure between the maximum and minimum values stated above, measured at
the appliance inlet pressure test point.
A union service cock MUST be fitted as close as practicable upstream of the heater to enable the gas train
to be removed for maintenance or repair.
It is essential to provide a flexible metallic hose, which must conform, to national or Local Regulations, to
connect the appliance to the gas supply. Minimum size to be ½" (12.7mm) bore.

Minimum supply pressure (Pmin): G30 - 20mbar
G31 - 25mbar
Note:- for appliance cat 3+ the governor is not operational
Gas connections: R - ½
3.2.2.1 The appliance should be connected to a permanent piped supply of LPG with pipes of adequate size to
achieve a gas supply pressure between the maximum and minimum valves stated above, measured at
the appliance inlet pressure test point.
3.2.3 The complete installation MUST be tested for soundness in accordance with National or Local
Regulations.
3.3 Electrical Supply
WARNING: THIS APPLIANCE MUST BE EARTHED
3.3.1 The electrical wiring to each heater must be installed in accordance with the latest or current National
