hello all, looking for advice on re-installing the gas fire to my abbey gt 214 1987 model, she's old but a great little van. When we bought her the gas fire been ripped out and capped off along with the carver cascade 2 water heater non of which i presume working, i'm looking at putting them back in, mainly the fire, we've installed a electric fan heater but not as a permanent fixture. from what i've looked at so far, (obtaining the manual from swift) is that originally the flue comes out the fire and up. Looking at the manual it's the carver SL3002. Just want opinions if i can get a fire with underfloor flue installed instead?
