Multifuel Stove

[skyplus]

I have had a 'Firewarm' multifuel stove for three years. I lit it for the first time
this season on Friday night, and during the night the glass cracked. Can anyone tell me:
(a) Why this happened?
(b) Is it safe to light it again with a crack in the glass?

Many thanks in advance

With a cracked glass there's a chance carbon monoxide fumes might leak into the room where the stove is.

Whilst I wouldn't know, I'd have thought there wasn't a problem continuing to use. Not like flames are going to pour through the crack and light up your carpet :-)

Wow, dangerous days when I used to sit in front of an open fire then ;-)
Make sure there's a battery in the sensor then.

If you got a carbon monoxide detector for the room it might give some reassurance.

It might be understandable if it cracked as soon as you lit it. Possibly reaching a high internal temperature before the glass had properly warmed up externally.
I can't think of any reason why it should crack overnight, while the stove is shut down and just "ticking over." I can only guess that it was pure bad luck.

Treated glass is under massive internal stress even while it's just sitting there. My front door exploded on a hot Summer's day a couple of months ago. No reason. I guess that, with your stove, the doorframe simply expanded at a different rate from the glass.

I would replace it as soon as possible. With the controls opened up, I doubt if there is much danger. Shut down overnight is rather different. The gases have a very small opening in which to escape. If the crack opens, CO might well escape.

A simple CO detector is always a good safeguard in any case.

Sometimes, i also face the same problem. But, it will not be dangerous of you crack in the glass again. Because, I use it again and again.
