Hello all. I was wondering if anyone could help me with a couple of questions (I had a search thru the forum but still am not sure). I had my chimney lined with a stainless steel liner recently, terminating in the hearth with a register plate and spigot. I'd just opened up a closed-up chimney breast and removed the old solid-fuel back-boiler I found there, and made good an inglenook for a Morso 04 stove I subsequently bought and have just installed myself last week. I used vitreous enamel stove pipe to connect the stove to the chimney liner spigot. I used the thin (1/4-1/2"?) fire rope supplied with the stove to pack the lower joint and bought 10mm (sorry don't know the inches) fire rope topack the upper, looser joint. I then used fire cement in a caulk type cartridge to finish off the joins. When I lit it for the first time it caught well and quickly established a good fire. But last night I tried it and after ten mins or so I noticed thin smoke issuing from somewhere around the top of the stove at a good rate. I experimented with the fire draught control to no avail and opened windows at either end of the room to ventilate. So finally! here are my questions... Was this caused by downdraught? I was sure I had made a pretty good fist of jointing the stove pipe that there shouldn't be smoke issuing, certainly not at the rate it was (almost as fast as from an open fire, it seemed). The liner guys fitted a rain cowl to the chimney pot - I don't know if that would help or hinder the draught. What can I do about that if it is downdraught? Sorry for the lengthy spiel but I'm a newcomer to all this so an unsure of how to proceed! Thanks.
