Please find below the TnC I received while registering the product for warranty. Note sure what is the benefit of warranty.
• The chimney should have been serviced and cleaned at regular intervals at-least once in two months by a Glen Authorized Service Centre failure to comply with this will render this warranty void. The cost of any such service will be borne by the customer.
• Only the parts covered under LTW will be replaced free. The labour charges for the replacement of under warranty parts will be borne by the customer. The visit charges (within municipal area only) of Rs. 250/- (subject to change from time to time) will be charged extra.
