Convective indoor and outdoor hybrid heating installation

An outdoor gas heater installation, the outdoor gas heater installation comprising a box, a lift mechanism, at least one duct and a convection outdoor gas heater, wherein:

• the box includes sides, a bottom and at least one outlet;
• the lift mechanism is housed within the box;
• the at least one duct is in fluid communication with the outlet;
• and
• the convective outdoor gas heater comprises:
• a top;
• a base;
• a pair of sides;
• a first wall which is attached to the top, the base and the pair of sides;
• a combustion chamber which includes combustion chamber wall and a combustion chamber outlet, the combustion chamber outlet proximate to the top or in the top, the combustion chamber wall spaced apart from the first wall to define a first interstitial passageway, the first interstitial passageway in fluid communication with the combustion chamber outlet;
• a gas burner assembly which is housed in the combustion chamber;
• a leg extending outward from the first wall;
• a second wall, which is attached to the pair of sides and the leg and is spaced apart from the first wall to define a second interstitial passageway, the second interstitial passageway in fluid communication with the first interstitial passageway;
• a base which supports the first wall, the second wall and the combustion chamber;
• a combustion air inlet in fluid communication with the combustion chamber;
• an air inlet in fluid communication with the second interstitial passageway;
• an air pressurizing device in fluid communication with the first interstitial passageway and the second interstitial passageway;
• and an outlet in the base which is in fluid communication with the first interstitial passageway, wherein the convective outdoor gas heater is mounted on the lift mechanism and in a stowed position is housed within the box and in an operational position, the base and the box form a manifold.
