87D1505

Safety Information

Please Read This Manual Before Installing and Using Fireplace

IMPORTANT: 

Read all instructions and warnings carefully before starting installation.  Failure to follow these instruc-

tions may result in a possible fire hazard and will void the warranty.

Description

The M400BFC fireplace is a  solid fuel, woodburning 
fireplace. The M400BFC is a balanced flue (closed 
combustion) heat-circulating fireplace which receives 
outside combustion air through the chimney system.
The M400BFC is a decorative fireplace which provides 
efficient supplemental heat compared to other wood 
burning fireplaces. It should not be used as a primary 
source of heat. 

CAUTION:

 Overloading the firebox with wood may re-

sult in overfiring and damage to refractory components, 
the grate and doors.

Precautions

MHSC fireplaces and component parts have been 
thoroughly tested and will operate safely when installed 
in accordance with instructions provided in this manual. 
Carefully read and understand all instructions 

before

 

beginning installation.
If you notice any damage to fireplace or component 
parts, immediately report damage to your Monessen 
dealer.
Only use MHSC components or the warranty will be 
voided and a fire hazard may be created.
MHSC warranty will be voided by and MHSC disclaims 
any responsibility for the following actions:

• 

Installation by any other than a qualified 
installer, preferably NFI or WETT (Canada) 
certified.

• 

Installation of any damaged fireplace or chim-
ney component;

• 

Modification of fireplace, chimney assembly 
or any component parts thereof; 

(except for 

chase flashings as detailed in MHSC Chimney 
Top installation instructions).

• 

Installation other than as instructed by MHSC; 
or

• 

Installation and/or use of any component part 
not manufactured or approved by MHSC in 
combination or assembly with a MHSC fire-
place system, notwithstanding any indepen-
dent testing laboratory or other third party 
approval of such component parts or acces-
sory.

Any such action may possibly cause a fire hazard.

Consult local building codes to ensure that you are in 
compliance 

before 

installing the fireplace.

This fireplace and chimney system must be vented to 
the out-of-doors.

Do not obstruct or modify air inlets/outlets in any 
manner. 
Do not install combustible materials on any of the 
black fireplace surround.
Burn only solid wood fuel or gas logs.
The M400BFC is intended for operation only with 
the doors closed.
Do not install a solid fuel burning insert or other 
products not specified for use with this fireplace.

Drafts

The fireplace should not be located in areas that create 
drafts (ie: frequently opened doors and central heating 
air inlets/outlets) that hamper the normal flow of air into 
the fire.

Gas Logs

If you plan to install a gas log, the gas line should be 
installed before framing the fireplace. The gas line must 
be installed by a certified gas line installer.

Proposition 65 Warning: 

Fuels used in gas, wood-

burning or oil fired appliances, and the products of 
combustion of such fuels, contain chemicals known 
to the State of California to cause cancer, birth de-
fects and other reproductive harm.
California Health & Safety Code Sec. 25249.6

WARNING: Check with your electronics manufac-
turer before installing a television or other electron-
ic device above this fireplace.
