Hi John, we cannot give gas advice, please see following paragraphs from forum rules:
Gas, Gas Appliances, Boilers and Central Heating Advice.
Any posts relating to gas, gas appliances, boilers and central heating should be posted in their relevant sections and not in the public domain.
We cannot and will not give advice on the installation or repair of boilers, cookers or ANY gas appliances for your own safety unless you can prove you are in the industry.
For in depth discussion on this subject we require you to join the GSR only forum, for which you must have a minimum of 10 posts, proof of membership with the registration body in force of your country of residence (We have a few ex pat’s dropping by occasionally!) and then undergo a small examination to prove to us you are keeping up with industry changes.
Providing gas-related advice to anybody who should not be touching gas and cannot prove their competence is unacceptable. We will take whatever action we deem appropriate to prevent such advice being given
