Dewhot | Gas geyser manual
WARNING
Never use an open flame to test for gas
leaks as this could result in property
damage, personal injury and or death.
VENTING/FLUEING
DO NOT connect the gas geyser to an
existing vent or chimney, it must be
vented/flued separately from any
other appliances.
When installing a gas geyser a minimum of
1 meter is required from any
venting system.
IMPORTANT TIPS
If the water flow is too slow, the gas
geyser will not ignite. Keep the shower
head/outlets clean from debris that
reduces flow rate.
To keep the water pressure balanced
add a 400-600kpa pressure regulating
valve on the cold water supply for
municipal water feeds. Install a shutoff
valve near the inlet of the gas geyser for
service and draining purposes.
Installation of demountables is
recommended on the hot and cold water
lines, so that the gas geyser may easily
be disconnected for servicing.
Install a non-return on the outlet of the
gas geyser to prevent water hammer.
Do not solder the HOT or COLD water
connections near to the gas geyser. If
solder connections are to be used, solder
the fitting to the adapter before fitting
the adapter to the water connections on
the geyser. Any heat applied to the water
supply fittings will permanently damage
the internal components of the gas geyser.
Hot water outlet connections between
the gas geyser and the usage points
should be as short as possible.
DO NOT use lead or plastic pipe. To
save energy and reduce heat loss we
recommend insulating the water piping.
NOTE The flow rate of hot water may
vary when more than two taps or
fixtures are being used at the same time.
