HEAT RECOVERY VENTILATION
Where a stove is to be installed in a dwelling with
Heat Recovery Ventilation (HRV) a number of
precautionary measures must be undertaken:
Should for example the delivery fan in the HRV unit
fail and the extraction fan in HRV fan continue to
run the HRV may create a pressure less than
atmospheric, this low pressure will effect the flue
pressure which is required to safely evacuate the
products of combustion from the stove.
1. Fit an adequately sized vent in the room to pre-
vent pressure less than atmospheric occurring.
The size should be established by closing all
windows and doors and then creating the
possible failure situation. Then open a window
in the room where the stove is fitted, slowly
until the pressure reaches atmospheric. The
size of the window opening should be
measured and a vent of the corresponding size
installed.
2. Fit a CO Alarm which has been approved to
EN 50291.
LOCATION
There are several conditions to be considered in
selecting a location for your Stanley Lismore Stove.
a. Position in the area to be heated, central
locations are usually best.
b. Allowances for proper clearances to
combustibles.
c. Allowances for proper clearances for mainte-
nance work.
From the Front 910mm
From the Back 750mm
From the Sides 550mm
From the Flue Pipe (Vertical no
heat shield fitted)
900mm
Mantle Clearance 760mm
Brick wall minimum clearance, but allow access
for controls and servicing. See Figs
7,8,9,10,11,12.
CLEARANCES TO COMBUSTIBLES
Maintain at least the following clearances to all
combustible material:
