AQUASTAT CALIBRATION
Only applicable for the WILDWOOD 20KW
fitted with the 53000Btu split saddle boiler
This stove has an Aquastat fitted as standard (diagram 15), and in conjunction with High and Low pipe
thermostats assists the stove to maintain the boiler temperature by automatically allowing either more or less air
into the fire chamber via the airwash depending on the Control Knob setting.
FITTING INSTRUCTIONS IF NOT FACTORY FITTED
The
copper capillary wire and phial are delicate and will be easily damaged if handled roughly.
With the
two M6 x 10 set screws and washers, fit the Aquastat control to its box at the rear of the 20Kw Stove, carefully fit
the phial flat end first into its boiler tapping. When viewed from the rear this is located immediately below the right
hand flow tapping and to the left of the Aquastat box, it is the tapping which is flattened at its top and has a
horizontal hole through it for the split pin to hold the phial in place.
CALIBRATION INSTRUCTIONS
The
Aquastat control must be calibrated
. It is the round flapper plate on this device that must be set. With the
stove alight, the boiler temperature at 55
0
C and the control knob in the middle (4-5) of it's range, the flap plate
should be just on the point of closing, adjust the position of the flap plate by means of the 5mm set screw and
nuts either side of the flap plate until this is achieved and then tighten the nuts.
OPERATION
Close both primary and secondary air inlets and set thermostat dial to number 6. This will now allow the stove to
work thermostatically according to the water temperature. Adjust the thermostat as required to suit demand.
