FLUE INSTALLATION
The stove must be installed using a Masport approved flue kit (including a ceiling plate).
Approved flue kits are supplied with detailed fitting instructions which, if followed, will
ensure that the installation will meet the required safety standards for performance and
durability.
FIREPLACE INSTALLATION
The model most convenient for this type of installation is the YUKON as it has a rear
flue outlet enabling the flue to be routed up the chimney. A straight flue socket will
usually be needed to replace the standard elbow normally fitted to the YUKON. The
baffle inside the firebox must be refitted as usual. When the straight socket is fitted, the
damper is fully open when its handle is in line with the flue, not when it is vertical as is
the case for the standard elbow.
A fireplace installation must meet the following requirements:-
• The fireplace and chimney must be thoroughly cleaned and checked for soundness.
• The chimney must not connect to a second fireplace.
• The joint between the chimney face and the fireplace surround must be checked and
sealed to prevent leakage if necessary.
• Where the fireplace is in a heat sensitive wall it must have a non-metallic heat resistant
surround extending at least 600mm each side of the recess centreline and up to at least
1400mm above the base of the fireplace recess.
• All safety clearances between the stove and any nearby heat-sensitive material
(including material above the stove), must be strictly maintained.
• A flue pipe must be fitted right up the chimney, and the space between the flue pipe
and chimney must be ventilated at the top. The area of this vent must be not less than
13,000mm

. The vent must be fitted with means to prevent significant ingress of water
and debris.
• We recommend fitting a horizontal register plate at the lower end of the chimney to
minimise room heat loss. The register plate should provide the same area of ventilation
as at the top of the chimney.
• Provision must be made to support the weight of the flue and to permit the free
expansion of the flue pipe when it heats up.
• The flue must be secured to the flue collar to prevent accidental separation.
• The hearth (floor protector) must extend at least 325mm beyond the feet in all
directions. If the hearth has to be extended to attain this dimension, the extension must
be as per one of our recommended constructions, and it must be fixed and sealed to the
existing hearth to prevent any possibility of a cinder falling through the joint to the floor
below.
MANTEL-SHELF SHIELDING
When the heater is installed in front of a fireplace, any heat sensitive material (such as a
mantel-piece) which protrudes from the face of the fireplace surround will need to be
completely shielded. This shielding is best provided by a sheet metal panel fastened
12mm from the face to be protected on heat resistant spacers. The inner edge of the
shield must abut the face of the fireplace surround and the outer edge and ends must
have an unobstructed 10mm gap to allow cooling air circulation.
