• The hanger plate supplied as standard with the boiler shall be
mounted on a full or half-full brick wall in accordance with the
connection screws and mounting template in compliance with its
technique and shall not be used for any other purpose.
• If different materials are used for mounting, the boiler will be out of
warranty.
• If the wall to be mounted on is not a brick wall, the durableness of
the support system must first be checked.
• The boiler must be mounted on a fire-resistant wall.
• It is recommended to mount the boiler between 1.8 - 2.2 m length
of hanger plate from the ground.
• In places where mounting area is limited, the boiler must be
mounted minimum 30 cm above the ground, with a space of
minimum 5 cm from the sides and 90cm from the front for easy
intervention of service technician.
• The boiler is not mounted in places with explosive, flammable
material and acid vapor.
• It is not mounted on sides of above cookers, ovens or heating
devices.
• Hermetic boilers can be mounted inside the furniture as well, but at
least 5 cm spacing should be left on their sides.
• It is advisable to connect the outlet of the boiler to the outlet line
by means of a transparent hose to prevent the possibility of water
coming from safety valve of boiler after mounting. If this is not
possible; do not put electronic devices, tools, parts and equipment
that can breakdown, rust, etc. under the boiler.
• Due to the above reasons, it is not recommended to put any
furniture under the boiler.

UP/10 2014 Edition 4 Installation of Gas Appliances in Industrial
and Commercial Premises
For BS 6644 and IGE UP 10 Installations the ventilation openings might
need to be increased if the following air temperatures are exceeded.
(@15°C Ambient)
High-Level (100mm Below Ceiling Level)
40°C
Mid-level (1500mm Flow Floor Level)
32°C
Low-Level (100mm Above Floor Level)
25°C
As a guide, reduction of air temperature may be achieved by increasing
the inlet and outlet air supply by 0.15 m
