Gas room heater question

[AlfromYC]

Hi, wondered if anyone could help.

I have a 1992 elddis wisp 510CD with a carver (1800 I think, that exits fumes from under the van) gas only fire. We have just spent 8 nights away in it, and the gas fire went out by itself twice during the week.

The gas bottle was full (calor lite), the stop tap for the gas fire was fully in the on position, and the all the other gas fired stuff was working A1. The van was fully serviced in Feb this year.

It was rather windy all week, we had the full awning up with the draft skirt just wondered if it was possible for the wind to blow the flame out?

Thanks in advance for any replies

Al.

Hello Al,

Unless you specifically asked your dealer to service the heater it is unlikely they did anything to it.

You are correct the carver 1800 series of heater do exit the flue gassed beneath the floor of the caravan. Various obstructions under the caravan or skirts can cause some strange air flows under the caravan, and yes they can affect the heater.

It is very unlikely the wind is blowing the flame out, but more likely preventing the flue gasses from leaving the exhaust, which baffles the flame.

If you look under the caravan you will find that the bottom most part of the heater is an oval fitting with the air intake. This is clamped to the bottom of the heater by two wing nuts. If you loosen (but do not remove them) you should find you can turn the direction the fitting. Ideally under normal circumstances, the air intake should sit beneath the exhaust (Galvanised rectangular box). This sets up a close to balanced flue arrangement, but in some set ups the air intake needed to be swung to clear under floor obstructions.

Always tighten the wing nuts after making an adjustment.

A word of warning, the Product you have is almost certainly be an SB 1800 model or a variation of it. Due to restrictions on the materials that were permitted to be used, the burner feed pipe does corrode. It is essential that this item is checked annually by your gas fitter. At the first signs of rusting it must be replaced. More recent versions of the pipe do have additional protection

Yes the wind can blow out the fire.

Yes it can blow out the fire, but, it shouldn't!

My experience is there is almost always something wrong, as yet only minor but it's unstable air conditions that show it up early.

With the 1800 series of which there are several various models, where fitted, the large air intake underneath is best spun as far away from the exhaust as possible

Thanks for all your replies.

Does anyone know if spares are still available for it?

(I wont take apart or try to repair it myself because I dont feel confident enough to do so)

Apart from gas feed pipes, in general spares are not required but what essentials are needed are still available. Problems only normally arise when something irreplaceable is damaged by someone not knowing what their doing, shall we say!

Thanks Gary. I spoke to the dealer who services my van, and he told me parts were not available (prob cos he wants to sell me a new heater at
