    Horizontal 3” Boiler Instructions v1.2 working pressure within the canister/tank – this is not recommended for less experienced operators/builders. If however, the canister/tank is allowed to get too hot, the pressure of the gas inside the canister/tank can become dangerously high and this must never be allowed to happen. It is important therefore that there is plenty of air space between it and any hot items such as boiler or steam pipes.
