BEFORE INSTALLING YOUR FIREPLACE
1) Please read this entire manual before you install and use your new wood fireplace. Failure to follow instructions may result in property damage,
bodily injury or even death. Install and use only in accordance with manufacturer’s installation and operating instructions.
2) Check your local building codes - Building Inspection Department. You may require a permit before installing your fireplace. Be aware that local codes and
regulations may override some items in the manual.
3) Notify your home insurance company that you plan to install a fireplace insert or freestanding heater.
4) THE FIREPLACE CAN GET VERY HOT. DO NOT INSTALL, PLACE OR POSITION TV’S, PAINTINGS, PICTURES, CANDLES, FURNITURE, DRAPES
OR ANY OTHER COMBUSTIBLE ITEMS ON THE WALL OR NEAR THE FIREPLACE.
5) ENSURE THERE ARE NO EXHAUST FANS WITHIN THE VICINITY OF THE FIREPLACE AS THIS CAN CAUSE THE FIREPLACE TO EMIT FUMES
BACK INTO THE ROOM.
6) ENSURE THERE IS ADEQUATE AIR SUPPLY WITHIN THE ROOM/AREA THE FIREPLACE IS BEING INSTALLED IN TO ENSURE PROPER OPERA-
TION OF THE FIREPLACE. INSTALL OPTIONAL OUTSIDE AIR KIT IF IN DOUBT.
7) EVALUATE THE LOCATION OF YOUR FIREPLACE AND OPTIONAL COMPONENTS. IT IS VERY IMPORTANT TO DETERMINE HOW THE FIREPLACE
IS GOING TO BE FINISHED. THE FEATURES YOU WOULD LIKE TO INCORPORATE SUCH AS THE OUTSIDE AIR KIT AND EXTERNAL FAN KITS
NEED TO BE EVALUATED PRIOR TO INSTALLATION.
8) DETERMINE WHAT THICKNESS OF YOUR DESIRED NON-COMBUSTIBLE FINISHING MATERIALS WILL BE INCLUDING THE HEAT RESISTANT
NON-COMBUSTIBLE BOARD. THIS PRE-DETERMINED THICKNESS WILL DICTATE THE POSITION OF THE SUPPORT FLANGES, FRAMING AND
OVERALL FINAL LOOK OF YOUR FIREPLACE.
9) Your fireplace is heavy and requires two or more people to move it safely. The fireplace can be badly damaged by mishandling and or injury can occur.
10) Do not connect the fireplace to a flue system servicing another appliance or an air distribution duct.
WARNING: CARELESS INSTALLATION IS THE MAJOR CAUSE OF SAFETY HAZARD. CHECK ALL LOCAL BUILDING AND SAFETY CODES BEFORE
INSTALLATION OF UNIT.
THE APPLIANCE, WHEN INSTALLED, MUST BE ELECTRICALLY GROUNDED IN ACCORDANCE WITH LOCAL CODES.
Regency Fireplaces are constructed with the highest quality materials and assembled under strict quality control procedures that ensure years of trouble free
and reliable performance.
It is important that you read this manual thoroughly and fully understand the safe installation and operating procedures. The more you understand the way
your Regency Fireplace operates, the more enjoyment you will experience from knowing that your unit is operating at peak performance.

Montrose Woodfire 7
installation
1) Never use petrol, petrol type lantern fuels, kerosene, charcoal lighter
fuel, or similar liquids to start or ‘freshen up’ a fire in your heater. Keep
all such liquids well away from the heater while it is in use.
2) Keep the door closed during operation and maintain all seals in
good condition.
3) Do not burn any quantities of paper, garbage, and never burn flam-
mable fluids such as petrol, naptha or engine oil in your heater.
4) If you have smoke detectors, prevent smoke spillage as this may
set off a false alarm.
5) Do not overfire heater. If the flue connector, flue baffle or the heater
top begin to glow, you are overfiring. Stop adding fuel and close the
draft control. Overfiring can cause extensive damage to your heater
including warpage and premature steel corrosion. Overfiring will void
your warranty.
6) Do not permit creosote or soot build-up in the flue system. Check
and clean flue at regular intervals. Failure to do so can result in a seri-
ous flue fire.
7) Your Regency heater can be very hot. You may be seriously burned
if you touch the heater while it is operating, keep children, clothing and
furniture away. Warn children of the burn hazard. For safety reasons
a guard around the fire is recommended.
8) The heater consumes air while operating, provide adequate ventila-
tion with an air duct or open a window while the heater is in use or use
optional outside air kit.
9) Do not use grates or andirons or other methods for supporting fuel.
Burn directly on the base or bricks where supplied.
10) Open the draft control fully for 10 to 15 seconds prior to slowly
opening the door when refuelling the fire.
11) Do not connect your unit to any air distribution duct.
12) Your wood fire should burn dry, standard firewood only. The use of
cut timber, plywood, “mill ends”, etc. is not allowed as this fuel can easily
overheat your wood fire. Evidence of excessive overheating will void
your warranty. As well, a large portion of sawmill waste is chemically
treated timber, which is illegal to burn in many areas. Salt drift wood
and chemically treated fire logs also must not be burned in your wood
fire.
13) DO NOT OPERATE WITH BROKEN GLASS.

WOOD FIREPLACE SPECIFICS AND MINIMUM CLEARANCES TO COMBUSTIBLES
Enclosure Ventilation
Unit cavity to have a minimum of two 20,000mm2 air vents must be
installed, one 300mm from the top of the enclosure and one 50mm
from the bottom of the enclosure to stop excessive heat built up
in the enclosure.
Wall Materials
Non-combustible material with a minimum thickness of 9mm must
be used on the front wall of the reduced enclosure. Non combustible
board and non combustible cladding to finish up to the standoff
brackets. Must maintain 20mm gap around entire face of the unit.
Please note: Non-combustible materials need to be fit for purpose
as wall temperatures can exceed 250o.
Hearth / Floor Protection Requirements
Hearth needs to be 6mm thick, 1475mm wide and 1,100mm deep to allow for 550mm leading
edge. We do recommend that your non-combustible hearth extends 900mm in front of the
unit. This allows the floor to be protected when the door is fully open in case of ember drop.
The appliance must be installed on a non-combustible stand 300mm above the hearth.
Cavity
Timber framing in the ceiling cavity must be a minimum of 1200mm above the zero box.

8. Install the support strips. The unit comes with four support strips. The
left and right sides are the same, and top and bottom are unique. Install
the top and side support strips with the slotted side on the unit. The
left and right should NOT be touching the floor. Secure with the screws
provided. Install the bottom small support flange and secure to the left
and right vertical ones. DO NOT TIGHTEN SCREWS on the top, left
and right support flanges.

9. Position the support flanges to the pre-determined thickness of the finish
material. The non-combustible finish materials and non-combustible board
are to sit up to the clean edge trim with standoff brackets. Using the scrap
pieces as a gauge position them so they are flush with the front edge
of the clean edge frame. Then slide the top support flange so it is tight
against the back of the non-combustible board/finish material and tighten
the screws. Do the same to the left and right sides.
THE SUPPORT FLANGES ARE NOW SETTOTHETHICKNESS OFTHE
FINISH MATERIAL.

10. Install the top front wall timber frame as per minimum clearances to com-
bustibles (page 9). Secure the top support flange to the vertical studs (left
& right sides), along with the left & right support flanges.
11. Install the non-combustible board. Ensure there are no seams on the top
and sides as these areas get extremely hot. Having no seams on the top
and side will prevent cracking. Use only high heat non-combustible board.
12. Install the final layer of non-combustible finishing material such as tile,
slate. Etc. ENSURE ALL ADHESIVES/ GLUES/ ETC ARE HIGH HEAT
RESISTANT. ALLOW BONDING AGENTS TO CURE PROPERLY BEFORE
FIRING UNIT.
13. Install the 30/50mm finishing trim by removing the deflector above the door.
Open the firebox door and remove the screws holding the deflector in place.
Remove the deflector and locate the finishing trim into position and reinstall
screws to hold both the trim and deflector in place. Install the remaining
screws to base of the finishing trim.

CLEARANCES
* Wall studs must be 407mm on centre for
mounting fan housing.
* Fan Housing: Maintain a (6mm) clearance
from fan housing to combustible material.
*
Wall Registers must be 102mm above floor
and / or 102mm below ceiling.
1) Determine the location of the air register/fan
