Safety Instructions

1.  Before  starting  the  MAGNUM  fireplace  and  DM  54 

chimney installation, read these installation instructions 

carefully to be sure you understand them completely. Failure 

to follow them could cause fireplace malfunction resulting in 

serious injury or property damage.

2. Always  check  local  building  codes  governing  fireplaces 

and fireplace installations. The MAGNUM fireplace and DM 

chimney  installation  must  comply  with  all  local,  regional, 

state and national codes and regulations.

3.  MAGNUM  fireplace  and  DM  54  chimney  systems  are 

intended  for  use  in  any  application  where  a  traditional 

masonry  type  fireplace  would  apply.  The  chimney  system 

must always vent vertically to the outside of the building.

4. Creosote and soot formation and the need for removal: 

When  wood  is  burned  slowly,  it  produces  tar  and  other 

organic  vapors  which  combine  with  expelled  moisture  to 

form creosote. The creosote vapors condense in the relatively 

cool chimney flue of a slow burning fire. As a result, creosote 

residue  accumulates  on  the  flue  lining.  When  ignited  this 

creosote makes an extremely hot fire.

 

Because of creosote and soot buildup it is necessary 

to inspect and clean the fireplace and chimney prior to use 

and periodically during the heating season. Cleaning of the 

fireplace and the chimney system should be done annually at 

a minimum. In colder climates, chimney cleaning may need 

to be done periodically throughout the heating season.

5. Before servicing, allow the fireplace to cool. Always shut 

off any electricity or gas to the fireplace while working on it. 

6. Use only solid fuel or natural or LP gas log sets in this 

unit. Do not use artificial wax based logs, chemical chimney 

cleaners or flame colorants in this fireplace.

7. Never use gasoline, kerosene, gasoline-type lantern fuel, 

charcoal lighter fluid, or similar liquids to start or “freshen 

up” a fire in this fireplace. Keep all flammable liquids at a safe 

distance from the fireplace.

8. Always keep the flue damper open when heat is present in 

the fireplace.

9.  Do  not  use  a  fireplace  insert  or  any  other  product  not 

specified for use with the MAGNUM fireplace and DM 54 

chimney  systems  unless  written  authorization  is  given  by 

Isokern. Failure to heed this warning may cause a fire hazard 

and will void the Isokern warranty.

10. This fireplace is not intended to heat an entire home or 

to be used as a primary heat source. It is designed to ensure 

homeowner comfort by providing supplemental heat to the 

room.

11. Always  ensure  that  an  adequate  supply  of  replacement 

combustion air from the outside of the house is accessible to 

the fire to support normal combustion. Fireplaces consume 

large volumes of air during the normal firing process. 

 

In the event the home is tightly sealed and has 

modern energy efficient features, the optional combustion air 

supply kits may not provide all the air required to support 

combustion and the proper flow of combustion gases up the 

chimney.

 

The manufacturer is not responsible for any smoking 

or related problems that may result from the lack of adequate 

air supply flowing into the house. It is the responsibility of 

the builder/contractor to ensure that adequate air supply has 

been provided for the fireplace.

12.  “Smoke  free”  operation  is  not  warranted  nor  is  the 

manufacturer responsible for inadequate system draft caused 

by mechanical systems, general construction conditions, 

inadequate  chimney  heights,  adverse  wind  conditions  or 

any unusual environmental conditions or factors beyond the 

manufacturer’s control.

Caution: 

When used with the MAGNUM fireplace system, 

all gas log sets must be operated with the damper clamped in 

the fully open position. This includes unlisted “vent free” log 

sets. Only listed “vent free” log sets may be operated with the 

damper in the closed position.

13. When in doubt about a component’s usability - has 

visible or suspected physical damage - consult your Isokern 

distributor or authorized Isokern representative for advice.
