INSTALLATION
• Before running the booster the machine should be cle-
aned thoroughly, taking particular care to make sure
that pulleys and the belt are free from abrasive dust
etc, which may have settled on the machine during in-
stallation.
• If the booster is in the boilerhouse then the ventilation
and air inlet louvres for the boiler will also serve for the
booster to keep the ambient temperature satisfactory,
providing the full recommendations for free area and
• Standard boosters are designed to operate in ambient
temperatures not exceeding 40°C. When the booster
is housed separately to the boiler, ventilation must be
provided to keep the ambient temperature below this.
Ventilation openings in this case must be sized relative
to any heat emitters in the room and the effects of solar
gain.
• The booster control enables the booster to work auto-
stop any excessive increase in operating temperature
and we recommend that the booster should only ope-
rate in conjunction with the burner. Prolonged periods
-
ase in temperature, shortening the life of the booster
and increasing service frequency. If however the plant
is required to work under such conditions, considerati-
on should be given to the use of a purpose-designed
bypass to dissipate the excess heat and the installation
of a twin duty stand-by system to allow for regular ins-
operated regularly or in rotation. If the booster is ope-
rating in rotation auto cycling may have been installed
as an option.
i
Do not test the fan chamber assembly by
hydraulic pressure: this practice will ine-
vitably damage the fan bearing assembly.
i
All booster assemblies are tested for gas
tightness by means of air at a pressure of
0.69 bar during manufacture.

-
proximately 450mm high to raise the unit to a conveni-
ent level.
• Noise attenuation and absence resonance are best
obtained by supporting the booster on anti-vibration
mounts.
• For the same reasons, connecting pipework needs to
be accurately aligned and properly supported. The use
booster and pipework is strongly recommended. These
-
work system and eliminate strain on the fan chamber.
NOTE:
Flexible piping should be examined by
the operator on a monthly basis. Change
if there are any signs of deterioration or
cracking.
• Changes in pipework sizing are best made close to the
booster ports. The use of expanders and reducers are
recommended to minimise pressure losses.
• Where it is necessary to reduce or increase pipe sizes,
by changing cross section of pipework in easy stages.
• Connections for pressure testing or for pressure swit-
ches should be located at points in the system where
there is not excessive turbulence i.e. where there is a
straight run of pipework at both sides of the switch (i.e.
at least 10 diameters of straight pipe).
NOTE:
If a gas booster is located in a meter/
governor room then the associated
electrical equipment, i.e:- control panel,
motor, pressure switches should be sui-
table for use in a Zone 2 area with group II
A gases (refer to BS4683, part 3).
