Summary

1.

 

WARNING:

 

 

Fire-Lite fireplace and Class “A” metal chimney systems 

will  only  draught  properly  when  they  are  installed  according 

to  the  instructions,  in  an  appropriate  location  and  with  the 

proper chimney height. Installing the fireplace according to the 

instructions, choosing an appropriate location, and choosing an 

appropriate chimney

height are the responsibility of the designer and the building 

contractor.

 

Tightly  insulated  and  sealed  homes,  two  story  interior 

spaces and high vaulted ceilings can cause negative air pressures 

within the house which can impair drafting performance. HVAC 

return air ducts near the fireplace opening will adversely affect the 

fireplace drafting performance.

 

It is the responsibility of the designer, the building 

contractor and their mechanical contractor to determine that the 

building’s internal air pressures are conducive to positive fireplace 

drafting.

 

Avoid  placing  any  fireplace  in  an  area  near  tall  trees, 

tall buildings, or high land masses. These structures can reduce 

ambient  air  flow  pressure  as  well  as  produce  down  draughts, 

either of which can impair fireplace drafting performance.

 

Earthcore  Industries  L.L.C.  does  not  warrant  drafting 

and is not responsible for it.

2. Magnum Fireplace and Fire-Lite Fireplace Curing 

Instructions:

 

It is critical that the Isokern masonry elements in the 

Fire-Lite firebox and smoke dome assembly be dry before firing 

of  the  unit.  Moisture  left  in  the  Fire-Lite  components  from 

exposure during storage and shipping, as well as moisture from 

the installation phase, must be eliminated before the unit is put to 

its intended use.

 

The first step in reducing the ambient moisture is to be 

sure that the completed Fire-Lite fireplace rest totally in a dried-in 

setting for a minimum of 28 days after construction of the unit is 

complete.

 

The next step in curing the Fire-Lite fireplace is to be 

sure that the first five or six fires are of short duration.

 

The first fire of the unit can take place once the minimum 

twenty-eight  day  drying  period  has  passed. This  fire  should  be 

especially short.

 

Start the first fire slowly with a small amount of paper 

and  kindling  (small  dry  wood  splits  or  twigs)  and  a  maximum 

load  of  four  to  six  pounds  of  dry  firewood,  estimated  to  be  no 

more than two or three logs each of about three inches (3”) to four 

inches (4”) diameter.

 

The first fire should burn for no more than thirty to sixty 

minutes and then allowed to go out. Do not refuel the fireplace 

during the first lighting.

 

A cooling off period of twenty-four hours, at a minimum, 

should follow the first fire.

 

The second fire should be the same as the first fire.

 

The second fire should burn for no more than thirty to 

sixty minutes and allowed to go out. Do not refuel the fireplace 

during the second lighting.

 

A  twenty-four  hour  cooling  off  period  must  be 

observed following second lighting.

After first and second fire, continue use of the unit with three 

or four small fires of short duration (sixty minutes or so) and 

small fuel load.

 

After  these  first  five  or  six  small  fires  of  short 

duration normal use of the fireplace can proceed. For normal 

use the maximum recommended fuel load is twelve to sixteen 

pounds of dry firewood at a time. This fuel load is considered 

to  be  approximately  three  to  five  cured  hardwood  logs  of 

about three inches (3”) to six inches (6”) in diameter. As the 

fire  burns  down,  refueling  should  be  only  one  or  two  logs 

added at a time.

Important:

 Do not burn construction debris or trash of any 

kind in the Fire-Lite fireplace.

 

Whereas it is not uncommon for construction debris 

and refuse to be burned in a fireplace by site personnel on 

a project that is under construction, this activity must be 

avoided.

 

It is the responsibility of the building contractor 

to insure that the required dry-in period is met and that the 

required lighting sequence is performed by the owner or by 

the owner’s agent.

3. Log grates are required for burning solid fuel in the 

Isokern fireplace.

 Grates allow for easy air flow up through 

the burning logs thus creating a more complete and efficient 

burning of the fuel.

4. How to Build a Fire:

 

First set the fireplace damper in the full open position. 

Begin laying the fire by placing several pieces of wadded up 

paper directly on the log grate. Place kindling (small splits of 

dry pine or other dry softwood) on top of the paper, enough 

to  loosely  cover  the  paper.  Next  arrange  several  small,  dry 

hardwood or softwood logs or log splits on top of the kindling 

layer.

 

Finally, arrange two or three larger hardwood logs 

(oak, hickory, etc.) or log splits on top of the stack.

Ignite the paper at the bottom of the stack. The burning paper 

will ignite the kindling which will, in turn, set the remaining 

fuel on fire.

 

Be sure to stack all firewood in such a way that it will 

settle into the log grate as the paper and kindling layers are 

burned away. Additional logs can be set onto the fire as each 

fueling burns down.

 

Ideally, fuel logs should be of a hardwood species 

that have been air dried for one year or longer. Use of cured or 

uncured pine logs and uncured hardwood logs for fuel should 

be avoided. Pine logs and uncured hardwood logs will tend 

to smolder and burn at relatively low temperatures producing 

high levels of soot and creosote.

Important:

 Do not throw, toss, jam, kick or otherwise force 

logs into the Standard fireplace.
