fbh firing sequence

[suffolk boy]

much against my better judgement i have bought another fan.so the weather for this week will be as follows.freezing to the point that you be able to create a walking stick by urinating.i will be driving a cold car during this.the part for the fbh will arrive in about a week we then be hit by a warm front making the fbh surplus to requirements plus pouring rain so i will not fancy fitting it due to a lack of a garage.
