Grimsby stove and finance Ltd 4M stove. Unknown manufacture number and spacing requirements

[Bkm91]

Hello, I just bought this stove off a friend for my workshop. I want to confirm the spacing requirements but I can't find a model number to search online. Any help would be greatly appreciated. Photos attached.

It says " Grimsby Stove and Furnace Ltd, Grimsby Ont" and "4M" on the top.

Unlisted stoves need 36" clearance in all directions. With proper shielding, this can be reduced to 12". This includes the side bench and door trim.

Note that the metal on the rear wall does not qualify but might if properly installed on 1" non-combustible spacers, with a 1" or larger gap at top and bottom.

After the difficult decision of what stove to buy has been made, you’ll need to install the stove safely. However good the stove is, it’s still not safe unless installed to manufacturers specifications.

First, review the owners guide that came with the stove. Discuss the installation with your retailer. If you have further questions, contact the technical service department of the manufacturer. The Hearth.com Forums (on this site) can also help you get answers about stove clearances.

Thank you! Yes the metal on the wall is screwed into 1" perforated steel tube on either side. And open at the top. Since the clearance requirement you listed is only 36" does that mean I can remove the top shield?

It may be the picture, but the rear shield does not appear to have at least a 1" gap at the bottom. This is necessary so that air can freely convect up behind the wall shield. If the stove is connected with single-wall stove pipe, then the ceiling shield may be necessary to reduce the stove pipe clearance from 18" to 9".

Thanks! Here are some better photos. The rear shield is 7' and is screwed into a 1inch 3' pipe on either side leaving a large gap on either side. Maybe I should trim a little more off the bottom

Yes, it's the wrong way to do it. There should be no horizontal, air blocking, attachments. The 1" shims need to be vertical and the shield open at top and bottom so that air can freely convect behind the shield.

Thank you! The shims are vertical but the top is blocked by the shield on the ceiling. I'll lower the shield on the wall so there is a gap before the ceiling shield. And I'll shorten the shield so it doesn't go all the way to the ground.
