The instructions state:
The vent must extend at least 3' (1m) above the highest point
where it passes through a roof of a building and at least 2’
(0.6m) higher than any part of a building within a horizontal
distance of 10' (3.05m) unless otherwise specified by the
(American) National Fuel Gas Code, ANSI Z223.1 or (Canada)
CAN/CGA-B149 Installation Code
The way I read this is that the vent tube must stick out of my roof by a minimum of 36". If this is true, why do you only need to have a horizontally vented unit protrude 12" from the side wall? It seems like the would be the same. I do not like the idea of a 36" tube sticking out of the top of my garage because the garage attached to the front of my house either vent would be very obvious from the street.
Any way around this?
