Draining and filling
Caution
this boiler works in a pressurised system which must only be drained, refilled and pressurised by
a
person competent to do so.
Note: if the pressure gauge indicates a loss of pressure that is less than 60 KPA (0.9 bar),
YOU MUST CONTACT YOUR
INSTALLER
unless you have been instructed by your installer on how to
re-pressurise the system correctly.

Replacement parts
If replacements parts are required, contact your Installer, Service Company or Thermalflow Ltd. Please
quote the name and model of your appliance. (Ref. Spare Parts List - section 1.8.1).
It is recommended that the Thermaflow has a safety and maintenance check on an annual
basis.
A pressure reducing valve must be fitted to the cold water inlet of the appliance if the
incoming pressure exceeds 300kPA (3 Bar).
The position of the outlet from the discharge pipe shall be visible to the occupants and
shall be positioned away from any electrical devices.
The position of discharge pipes, (Tundish), drain valves and motorised valves etc, must
be positioned away from electrical components.
The water may drip from the discharge pipe of the pressure-relief device and must be left
open to the atmosphere.
The pressure relief device must be operated regularly to remove lime deposits and to
verify that it is not blocked.
The discharge pipe connected to the pressure-relief device must be installed in a
continuously downward direction and in a frost free environment.
DANGER:
Failure to operate the relief valve easing gear at least every six months may
result in the water heater exploding. Continuous leakage of water from the valve may
indicate a problem with the water heater
IMPORTANT:
If any external heat sources are being connected to the water heater, they
must be connected as detailed in this instruction manual. There must be temperature
control thermostats fitted to control each heat source and must be set to a
maximum
temperature of 80
⁰
C
