This device gives protection against both high and low pressures and is the safest method of installation.
This device also enables the following:
1.
Provision of an extra fusible plug at the top.
2.
Provision for accessories like Dead Weight Valve, vacuum relief valve etc.
3.
Non-pressure type installation.
NON-RETURN DEVICE: There is a siphon hole on the inlet pipe inside the inner tanks of all Bajaj Storage Water
Heaters. When pressure inside the tank becomes low, this siphon hole prevents back flow of water. It acts as a non
return device up to a certain level of low pressure. Thus it prevents collapse of the tank due to vacuum formation.

THE HOW AND WHERE OF INSTALLATION AND OPERATION
A.
Fix the Water heater in a perfectly straight position at a suitable height from the floor. While fixing the
horizontal wall models the inlet and the outlet pipes should be on the right side of the person fixing it.
B.
There should be enough space around the heater for easy installation and servicing.
C.
Make sure that supporting walls or fixture are strong enough to carry the weight of the heater when it is
completely filled with water.
D.
A typical installation (for vertical and horizontal mountings) is shown in Fig.
2, 3, 4 & 5. For overall and mounting dimensions please refer the technical
specifications table.
E.
There should be a minimum space of 50 cm between the top of the heater
and the roof. This is to make sure that the heater can be removed and
taken out when necessary.
F.
The heater should be saved from being damaged by splashing of water.
Therefore, keep a minimum space of about 1.8 m. between the floor and
bottom of the heater.
G.
When the mounting is horizontal, keep a minimum space of 50 cm between
the wall and inlet/outlet pipes so that parts can be easily removed for
servicing etc.
H.
INSTALL A VRV (VACUUM RELIEF VALVE) IN CASE THE WATER HEATER IS
INSTALLED IN MULTI STOREYED BUILDING.
WATER SUPPLY:
A.
You can connect the heater directly to municipal water supply or the water
tank on top of your house. But take care that the distance between the
heater unit and the tank is not more than 70 feet. This is equivalent to 30
P.S.I. or 2.1 Kg/cm
2
pressure.
B.
If the height is more, use a Pressure reducing valve at the inlet.
C.
The water pressure should also not be too low. The minimum distance
between the heater and the water supply tank should be at least 2 metres.
D.
WHEREVER POSSIBLE YOU SHOULD INSTALL THE VENT PIPE FROM THE
TOP OF THE HEATER UP TO THE LEVEL OF THE WATER SUPPLY TANK. THERE, IT SHOULD BE LEFT OPEN TO
THE ATMOSPHERE. THIS IS THE SAFEST METHOD OF INSTALLATION.
