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
OPERATION 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 FACEPLATE, OUTSIDE AIR AND FAN KIT NEED TO BE
EVALUATED.
8) DETERMINE WHAT THE THICKNESS OF YOUR DESIRED NON-COMBUSTIBLE FINISHING MATERIALS WILL BE INCLUDING THE
NON-COMBUSTIBLE BOARD. THIS PRE-DETERMINED THICKNESS WILL DICTATE THE POSITION OF THE NAILING 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.

Wall Cladding
Non-Combustible material such as 9mm cement sheeting
must be used on front wall of zero enclosure
Hearth Requirements
Hearth needs to be 6mm thick, 1470mm wide and 995mm deep to allow for 300mm leading
edge. We do recommend that your non-combustible hearth extends 900mm in front of the unit.
This allows the oor to be protected when the door is fully open in case of ember drop.
Floor Protection
The oor protector must be minimum of 300mm deep in front of the appliance base. However it
is highly recommended due to the width of the appliance door that this dimension is increased
of ember or hot ash spillage
The appliance must be installed on a non-combustible stand 300mm above the hearth.
