    I have a good friend that has a Heatilator TD46B1 fireplace in his house. It is installed in a very large great room with a Monassen vent free log set in it. His family is complaining that they can feel virtually no heat even when the log set is on high with the damper closed. We have discussed the possibility of installing either a wood or gas insert into this fireplace. His wife has vetoed the wood option. Are there any ideas on a good gas alternative that will fit this fireplace. I have installed several wood inserts and am well versed on installing gas piping but I do not know the first thing about gas inserts. Any help would be greatly appreciated, Jim

    You'll have to determine what your actual opening will be when you remove
    some or all of the guts from the Heatilator. Once you know what will fit,
    then you can decide which ones the woman of the house likes.
    Make sure that the surround is correctly sized to cover whatever opening
    is left after the insert is in. This may also require a firebox riser to make
    up for any excess in the opening height.
    If the damper unit in the vent system is large enough, you may be able to
    leave it in place, & slip the co-linear liners by, but it's best to remove the
    damper plate (Sawzall) so you can jam some unfaced fiberglass insulation in there
    around & between the liners. Once you remove the refractory material from
    the Heatilator, you may find that there are gas "knock-outs" on either sidewall
    for gas line access.
    So, basically, you run the liners down the vent, secure the cap at the top &
    insulate the bottom. It's a good idea to ID the exhaust side cuz if you mix
    them up at final vent hookup the wife's not gonna like it.
    Run the gas line into & thru the box so you can make your connections to the
    insert before you install it. I always pull enough gas line thru so that it reaches
    the front of the hearth.
    You'll also want to run an electrical feed in at this time for the blower unit or the IPI.
    Tapcon or Zipscrew a metal box to the floor of the Heatilator somewhere clear of the insert.
    Install an outlet & cover plate.
    It's also a good idea to use a piece of the cardboard packaging to set under the unit
    to prevent damage to the hearth as you jockey it around.
    Set the box in the opening & bleed the gas line while there's nothing in the way
    & you can get your nose in there to smell the fuel.
    Plug in the lead from the insert.
    Light the pilot.
    Set up the refractories/embers/logs.
    Install the glass, then the surround, then the front.
    Make your adjustments on the pilot (if necessary)& install the T-Stat/remote.
    Once the newness of the unit burns off & the paint cures, warmth & happiness!

    Bob, Thanks for the info. I guess my biggest question was do I install an insert into this fireplace as is? I understand the need to get the intake and exhaust past the damper, which may mean removing it. I was thinking I would leave the refactory panels in place, but I guess I could remove them for more room if that is acceptable. Are there any Heatilator dealers in this section of the forum that may know what would be a good fit in this unit? Thanks, Jim
