3. This applian e must be mounted onto a non- ombustible wall or tailored stand, using the rear wall
bra ket and spa ing s rews provided.
4. Combustible walls must not protrude past the front of the applian e.
5. This applian e must not be mounted on a ombustible surfa e or metal surfa e, as radiated heat will
ause these surfa es to be ome extremely hot.
6. Caution should be taken as intense heat is emitted at the bottom front of the applian e.
7. Components having adjustments prote ted (e.g. paint sealed) by manufa turer are only allowed to
be adjusted by an authorised servi e agent. They are not to be adjusted by the installation person.
8. The unit should be mounted under an extra tion hood in omplian e with all lo al regulations.
In the event that the unit is not mounted under an extraction hood, the installer must ensure
that all regulations are met and that there is an unobstructed minimum distance of 750mm
from the top surface of the unit to the ceiling, which must be of non-combustible material.
NOTE: Do not obstruct or block the appliances flue. Never directly connect a ventilation
system to the appliance flue outlet.
Clearances
NOTE: Only non-combustible materials can be used in close proximity to this appliance.
This unit must be installed on a non- ombustible wall or tailored stand with the following learan es;
* We re ommend allowing a learan e of 100mm on either side of the applian e to allow a ess to the
side panels for servi ing purposes.
** Using the wall mounting a essories provided with this applian e.
*** Top learan e to eiling is subje t to all lo al regulation requirements.

Wall Mounting (to non-combustible wall only)
1. Fix the wall mounting bra ket to the wall with six s rews, in su h a position that the top of the
bra ket is level and at least 945mm (38”) above any surfa e beneath the unit. This will ensure that
the bottom of the Salamander is at least 600mm (24”) above any surfa e.
2. Fit the two bla k plasti spa ers to the top
rear orners of the unit. Leave them
uns rewed by approximately 5mm.
3. Fit the two adjusting s rews / bolts into the
nutserts at the bottom rear orners of the
unit. These should protrude approximately
30mm from the rear of the Salamander.
4. Lift the Salamander onto the wall bra ket,
lining up the bla k plasti spa ers on the
salamander with the mounting not hes in the
bra ket.
5. Lower the Salamander onto the mounting bra ket.
6. Tighten the bla k spa ers se urely and adjust the

Gas Connection
NOTE: ALL GAS FITTING MUST ONLY BE CARRIED OUT BY A QUALIFIED SERVICE PERSON.
1. Blue Seal Salamanders do not require an ele tri al onne tion, as they fun tion totally on the gas
supply only.
2. It is essential that the gas supply is orre t for the Salamander to be installed and that adequate
supply pressure and volume are available. The following he ks should therefore be made before
installation:-
a. Gas Type the applian e has been
supplied for, is shown on a
oloured sti kers lo ated above
the gas onne tion and next to the
rating plate. Che k that this is
orre t for the gas supply the
applian e is being installed for.
The gas onversion pro edure is
detailed in this manual.
b. Supply Pressure required for this
applian e is shown in the
“Spe ifi ations” se tion of this
manual. Che k the gas supply to
ensure adequate supply pressure
exists.
. Input Rate of this applian e is stated on the Rating Plate and in the “Spe ifi ations” se tion of
this manual. The input rate should be he ked against the available supply line apa ity.
Particular note should be taken if the salamander is being added to an existing
installation.
NOTE: It is important that adequately sized piping runs di-
rectly to the connection joint on the appliance with as
few tees and elbows as possible to give maximum
supply volume.
3. Fit the gas regulator supplied, into the gas supply
line as lose to the applian e as possible.
The regulator onne tions are 1/2" BSP female.
The onne tion to the applian e is 1/2" BSP male.
(Refer to the the “Spe ifi ations” se tion for the gas
supply lo ation dimensions).
NOTE: A Manual Isolation Valve must be fitted to the individ-
ual appliance supply line.
4. Ensure the regulator has the orre t olour spring fitted for the gas type, as detailed in the
“Spe ifi ations” table. Opposite gas type repla ement spring is part of the gas onversion kit
supplied.
5. Corre tly lo ate the applian e into its final operating position and using a spirit level, adjust the legs
so that the unit is level and at the orre t height.
