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 FINISH TRIM, 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 PREDETERMINED 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.

Mansﬁeld L850B ST 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

serious 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) 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.
