What are the Combustion and Ventilation air requirements?
If the installation is using room air for combustion it shall be sized in accordance with the CSA B-149-10 Code book. In general, you require 1 sq. in. of free opening per 7,000 BTU’s up to an installed 1,000,000 BTU’s. You then allow 1 sq. in. of free opening for every 14,000 BTU’s install over 1,000,000. Remember, these areas are free opening space. Some louvers and grilles can equal up to a 50% reduction. Check with the manufacturer to see what reduction you must calculate. (ie: a 10×10 inch opening equals 100 sq. in. Install a grille and now it becomes 100 x 50%, which equals 50 sq. in.)
Can I use glycol in a Lochinvar boiler?
Yes, all Lochinvar boilers are manufactured to accommodate the addition of glycol. Use only inhibited propylene glycol solutions, which are specifically formulated for hydronic systems. Ethylene glycol is toxic and can attack gaskets and seals used in hydronic systems.
Is there any “Special” venting requirements for condensing boilers?
Yes there is. In Canada there have been special requirements set out by either the province or in some cases the municipality. Most provinces have mandated the use of “ULC S636 approved CPVC vent material” only. You may also select AL29-4C Stainless Steel or approved polypropolene materials. Check with the local authority having jurisdiction.
What type of Vent material is required?
Depending on which Lochinvar product you are installing please refer to the Manufacturers venting instructions found in every Installation manual. In Canada, we also follow the guide lines set out in the CSA B-149-10 Code book IF the installation is going to require Catagory One vent material. If the installation will require Catagory II, III, or IV vent material, we follow the directions printed in the manual from Lochinvar.
