mostat to the flow pipe of the gravity circuit and
wiring it into the pump control will ensure rapid cir-
culation of the hot water.
PIPE THERMOSTAT
The fitting of a pipe thermostat to the flow pipe is
essential in order to activate the water circulation
pump when the water reaches the selected temper-
ature.
When the water temperature falls below the select-
ed temperature the pipe thermostat will cut off the
water circulation pump in order to allow the boiler to
recover.
OPERATING INSTRUCTIONS
COAL BURNING
LIGHTING THE FIRE
Thoroughly check all pipe work for leaks, especially
the pipe connections to the boiler before lighting.
Allow the stove to build up heat slowly at first.
Check that all dampers and catches are operating
correctly and ensure that all flue connections are
thoroughly sealed.
Fully open the Spin Valve and Back Air Valve and
kindle with paper and sticks in the usual way and
ignite by using a taper or rolled wad of paper. Under
no circumstances should any inflammable liquid i.e.
petrol, paraffin etc. be used to light the fire. When
the fire is well established adjust the spin valve and
back air valve. Add fuel to the firebox as required
and adjust the air valves to suit current require-
ments.
When refuelling open the spin valve before opening
the door as this will help to eliminate smoking, after-
wards be sure to reset the spin valve and back air
valve to get maximum output from the boiler. Never
pack fuel tightly or fill the firebox to capacity. A low
INJECTOR TEE
Where the gravity and central heating circuits join
together to return the stove we recommended the
use of an injector tee connection, situation as close
to the unit as possible. This type of tee encourages
a stable flow of hot water through both circuits and
helps to prevent priority being given to the stronger
flow, which is most commonly the pumped central
heating circuit. This way, there will be no shortage
of hot water to the taps when the heating is on.
WATER CIRCUIT TEMPERATURE
The return water temperature should be maintained
at not less than 40oC so as to avoid condensation
on the boiler and return piping. Fitting a pipe ther-
