15" Tall, 16" Wide, 14" Deep. Approximate shipping weight in box: 3/4" construction weighs 25 lbs. 1" construction weighs 44 lbs.
Fireplace size requirements for the M-4 grate:
The rear wall of the fireplace must be a minimum of 16" wide (dimension A), the fireplace floor must be a minimum of 16" deep (dimension B), the height of the fireplace front opening should be a minimum of 25" (dimension C) to allow adequate clearance to easily load firewood onto the grate. If your opening is less than 25" in height or your floor is less than 16" in depth, you should consider one of our shorter "S" series grates instead. See more sizing information on our measuring guide page.
Fireplace construction requirements for the M-4 grate:
It is important to understand that the Wall of Fire grate is a one sided unit. This means that the burning firewood is positioned between the grate and the rear wall of the fireplace. Having the firewood in direct contact with the back wall of the fireplace will significantly increase the temperature of the firebrick and may cause brick and mortar fatigue over time. Because of this we highly recommend you also purchase a fireback to shield the back wall of the fireplace from excessive heat. If you are planning to use a Wall of Fire grate in any non mason built fireplace such as a pre-fab, zero clearance, or metal fireplace, the addition of a fireback is absolutely mandatory.
